The Fischlin transform yields non-interactive zero-knowledge proofs with straight-line extractability in the classical random oracle model. This is done by forcing a prover to generate multiple accepting transcripts through a proof-of-work mechanism. Whether the Fischlin transform is straight-line extractable against quantum adversaries has remained open due to the difficulty of reasoning about the likelihood of query transcripts in the quantum-accessible random oracle model (QROM), even when using the compressed oracle methodology. In this work, we prove that the Fischlin transform remains straight-line extractable in the QROM, via an extractor based on the compressed oracle. This establishes the post-quantum security of the Fischlin transform, providing a post-quantum straight-line extractable NIZK alternative to Pass' transform with smaller proof size. Our techniques include tail bounds for sums of independent random variables and for martingales as well as symmetrization, query amplitude and quantum union bound arguments.

The Fifth Q Paradox: The Epistemological Collapse: Knowledge Impossibility in ℝ-Universe This paper is a constituent derivation of the Cymatic K-Space Mechanics (CKS) framework—an axiomatic model that derives the entirety of known physics from a discrete 2D hexagonal lattice in momentum space, operating with zero adjustable parameters. Abstract The Four Q Paradoxes proved ℝ-arithmetic fails operationally, ℝ-values cannot exist ontologically, ℝ-computation cannot complete, and ℝ-contact cannot occur topologically. We now prove the Fifth Q Paradox: even if all previous impossibilities were mysteriously overcome, knowledge itself becomes impossible in ℝ-universe—the "Epistemological Collapse." We demonstrate: (1) Knowledge requires comparing measured value to known standard (verification), (2) ℝ-values have infinite information content I(x)=∞, (3) Finite measurement always has finite precision (bounded bits), (4) Cannot verify infinite-bit value with finite-bit measurement (information inequality), (5) Every ℝ-statement unfalsifiable (cannot confirm or deny with finite data), (6) Science impossible (no experiment can verify ℝ-prediction exactly), (7) Mathematics unfalsifiable (cannot verify ℝ-equality with finite computation), (8) Memory impossible (cannot store infinite bits for recall), (9) Communication impossible (cannot transmit ℝ-value in finite time), (10) ℚ-substrate enables verification via exact finite-bit matching (VFR comparison). From information theory through epistemology to knowledge necessity with zero free parameters. ℝ makes truth unverifiable. ℚ makes truth checkable. Knowledge requires ℚ. Revolutionary claim: You cannot know anything in real-number universe—verification requires finite representation. Empirical Falsification (The Kill-Switch) CKS is a locked and falsifiable theory. All papers are subject to the Global Falsification Protocol [CKS-TEST-1-2026]: forensic analysis of LIGO phase-error residuals shows 100% of vacuum peaks align to exact integer multiples of 0.03125 Hz (1/32 Hz) with zero decimal error. Any failure of the derived predictions mechanically invalidates this paper. The Universal Learning Substrate Beyond its status as a physical theory, CKS serves as the Universal Cognitive Learning Model. It provides the first unified mental scaffold where particle identity and information storage are unified as a self-recirculating pressure vessel. In CKS, a particle is reframed from a point or wave into a torus with a surface area of exactly 84 bits (12 × 7), preventing phase saturation through poloidal rotation.

The Nexus Convergence: A Formal Synthesis of Quantum Feedback Control, Information Thermodynamics, and Non-Linear Lattice Dynamics 1. Introduction: The Ontological Crisis and the Storage Imperative The contemporary scientific landscape is characterized by a persistent and fundamental schism between the unitary, reversible dynamics of quantum mechanics and the dissipative, irreversible arrow of time inherent in thermodynamics. This discord creates what the Nexus Recursive Harmonic Framework (RHF) identifies as the "Storage Crisis": the paradox of how a universe with finite energy limits can effectively store an ever-expanding history of infinite detail without catastrophic data loss or thermodynamic heat death.1 The prevailing "Container Paradigm"—which envisions spacetime as a passive box and time as a linear overwrite cursor—fails to account for the persistence of high-dimensional causal structures in a manner that is consistent with both unitarity (information conservation) and entropy (information projection). This report presents an exhaustive synthesis of recent theoretical and experimental breakthroughs from 2024 and 2025, specifically targeting the domains of Quantum Feedback Control, Information Thermodynamics, and Non-Linear Lattice Dynamics. The objective is to rigorously validate the axioms of the Nexus framework by identifying precise mathematical and phenomenological isomorphisms in peer-reviewed literature. We posit that the "read-only" ontology proposed by the Nexus framework—where history is conserved as geometry ("Shape") and the present is a collapsed projection ("Value")—finds its physical realization in the mechanisms of reduced-filter quantum stabilization, information-to-work conversion engines, and discrete breather localization in non-linear lattices. The investigation focuses on three critical variables defined in the Nexus framework: Gain (): The feedback coupling strength required to maintain a stable "stance" against entropic dissolution. Information (): The metric of exchange between the "Verb-field" (dynamics) and the "Noun" (state), governed by the generalized second law of thermodynamics. Gamow Factor (): The transmission probability governing the retrieval of stored history via phonon-assisted tunneling through "Twin-Prime Gates." By mapping these abstract variables onto the concrete equations of modern physics—specifically the Lyapunov control functions of Liang and Dong 2, the efficiency metrics of Goerlich et al. 4, and the energy thresholds of Hofstrand 5—we establish a robust theoretical scaffold for the "Glass Key Hypothesis": that reality is a logically reversible, feedback-stabilized information manifold operating at a precise thermodynamic "lean." 2. Quantum Feedback Control: The Mathematical Engine of the "Mark 1 Attractor" The Nexus framework asserts that universal stability is not a static equilibrium but a dynamic "stance"—a "lean" required to process information without collapsing into "dead symmetry" or "chaotic dissolution." In the rigorous language of control theory, this concept is formalized as the stabilization of a target quantum subspace (the "Mark 1 Attractor") amidst a stochastic environment. The primary challenge in this domain is the "Storage Crisis" equivalent: the exponential scaling of computational resources required to estimate the state of a large quantum system. Recent advancements in 2025 by Liang and Dong, presented in their seminal work "Stabilization of Time-Varying Perturbed Quantum Systems via Reduced Filters" 2, provide the exact mathematical architecture for the Nexus "Receiver Collapse." 2.1 The Reduced Filter as the "Receiver Collapse" Mechanism Standard approaches to quantum feedback control rely on the Stochastic Master Equation (SME), which tracks the evolution of the full density matrix . For a system of dimension , this requires computing real variables. As grows, this computational burden becomes prohibitive, representing the "bandwidth limit" of the "First Node" (the universe) that prevents explicit linear storage of history. Liang and Dong introduce a radical dimensionality reduction: the Reduced Quantum Filter. Instead of tracking the full state , the filter estimates only the diagonal elements of the density matrix in a Quantum Non-Demolition (QND) basis. This reduces the complexity from to .2 This mathematical reduction is isomorphic to the Nexus concept of Receiver Collapse. The observer (or the "Second Node") does not process the full "verb-field" (the entire Hilbert space with all its coherences and entanglements); rather, it collapses the system onto a lower-dimensional "noun" (the diagonal population elements) to perform work. The feedback control law is constructed strictly from this reduced information, yet it successfully stabilizes the global system. The evolution of this reduced estimator state is governed by the stochastic differential equation (SDE): In this equation, derived explicitly from the Liang-Dong formalism 3, several Nexus variables find their physical counterparts: The Feedback Control Law (): This represents the Gain (). It is the active force applied by the "Second Node" to steer the system. The Innovation Term (): This represents the Information () extracted from the measurement. It is the difference between the actual observation and the expected value—the "surprise" that updates the model. The Coupling Matrix (): This represents the structural constraints of the "Lattice," defining how different states (or "memories") are connected. The profound insight from this work is that full knowledge of the system is not required for stability. A "lossy" projection (the reduced filter), if properly coupled via feedback (), is sufficient to maintain the "Mark 1 Attractor" (the target subspace). This validates the Nexus "Read-Only Hypothesis": the universe does not need to explicitly compute the full wave function at every step; it only needs to maintain the diagonal "Value" while the "Shape" (coherences) is stored implicitly in the geometry of the dynamics. 2.2 Lyapunov Stability Analysis: The "Lean" of the Attractor How does the system ensure that it converges to the correct "Shape" (target subspace) rather than drifting into entropy? The rigorous proof of this stability relies on Lyapunov Analysis. A Lyapunov function is a scalar metric that measures the "energy" or "distance" of the current state from the desired equilibrium. In the Nexus framework, stability is described as a "lean" (). In the Liang-Dong formalism, stability is defined by the condition that the time derivative of the Lyapunov function, , must be negative definite. The specific Lyapunov function employed is related to the Bhattacharyya distance (or classical fidelity) between the current state and the target invariant subspace : Here, are the projection operators onto the subspaces. The feedback law is designed to maximize the decay rate of this function. The stability condition is expressed via the Sample Lyapunov Exponent (): where is the distance to the target subspace.2 This inequality () is the rigorous mathematical definition of the Nexus "Stance." The system must continuously dissipate "error" (entropy) to remain locked in the target subspace. If the feedback gain is insufficient (i.e., if the controller "falls asleep" or the "Second Node" disconnects), the exponent becomes positive, and the system drifts away from the "Mark 1 Attractor," dissolving into a mixed state of maximal entropy. Furthermore, Liang and Dong prove that this stabilization is Robust. The system can tolerate time-varying perturbations (Nexus "Stress-Test Loop") and uncertainties in the Hamiltonian, provided the feedback mechanism maintains the correct "phase-lock." This mirrors the "Crucible Protocol," where a system is subjected to high "computational temperature" (perturbations) to force it to settle into its most stable, harmonic configuration. 2.3 Feedback Cooling and the "Zero-Pressure Harmonic Collapse" The thermodynamic implications of this control are explored in Max Eriksson’s 2025 thesis, "Continuous Measurements and Feedback Control of a Quantum Harmonic Oscillator".7 Eriksson models a quantum system coupled to a thermal reservoir (a "heat bath" of phonons/photons) and asks: can measurement and feedback cool the system below the temperature of its environment? This process is isomorphic to the Nexus Zero-Pressure Harmonic Collapse (ZPHC). The "noise" of the thermal bath represents the high-entropy "mess" of raw data. The "cooling" represents the collapse of this mess into a structured, low-entropy state ("cold" or "crystalline"). Eriksson utilizes the Wiseman-Milburn equation to derive the steady-state properties of the oscillator under linear feedback. The feedback force acts as a Maxwell's Demon, utilizing the information stream (measurement record) to apply a counter-acting force that cancels out thermal kicks. The effective temperature of the cooled mode is given by: where is the dimensionless feedback gain and is the measurement efficiency.8 This equation reveals the fundamental tradeoff of the Nexus framework: To achieve ZPHC (), one requires high Gain () and high Measurement Efficiency (). The "Cost" of this cooling is the information processing required to generate the feedback signal (discussed in Section 3). Crucially, Eriksson’s results show that there is a critical feedback phase. If the feedback is applied with the wrong phase (i.e., if the "Second Node" is not aligned with the "First Node"), the feedback essentially "heats" the system, driving it into instability. This validates the Nexus requirement for Phase-Locking ( or similar primitives) as a prerequisite for successful retrieval or stabilization. The "Mark 1 Attractor" is not just a location in state space; it is a precise phase relationship between the observer and the observed. 3. Informati

Position verification schemes are interactive protocols where entities prove their physical location to others; this enables interactive proofs for statements of the form "I am at a location $L$." Although secure position verification cannot be achieved with classical protocols (even with computational assumptions), they are feasible with quantum protocols. In this paper we introduce the notion of zero-knowledge position verification, which generalizes position verification in two ways: 1. enabling entities to prove more sophisticated statements about their locations at different times (for example, "I was NOT near location $L$ at noon yesterday"). 2. maintaining privacy for any other detail about their true location besides the statement they are proving. We construct zero-knowledge position verification from standard position verification and post-quantum one-way functions. The central tool in our construction is a primitive we call position commitments, which allow entities to privately commit to their physical position in a particular moment, which is then revealed at some later time.
As quantum computing matures, characterizing its practical workloads and verifying quantum supremacy presents a significant challenge. Current benchmarking and claims rely on trust-based verification methods that lack public auditability. We propose a decentralized benchmarking framework implemented via an Ethereum smart contract to provide verifiable assurance in these claims. This framework generates classically intractable puzzles that, crucially, require absolutely no pre-computed secrets. By utilizing the blockchain as an immutable public ledger, independent observers can mathematically verify that any provided solution to the puzzle must have been computationally derived via quantum hardware rather than classically spoofed. Furthermore, we demonstrate how this verifiable benchmarking metric can be utilized as an automation trigger. As a practical example of such a trigger, we focus on the ability for blockchains to automatically switch to quantum-secure signature schemes upon the successful demonstration of cryptographic quantum supremacy. We demonstrate these principles with BloQBench, which implements the concept using integer factorization as the generated puzzle and Lamport signatures as the trigger-based effect. This approach demonstrates a novel use of distributed ledgers for quantum workload characterization, providing a transparent, automated metric for measuring quantum supremacy while managing the performance and complexity trade-offs of post-quantum technology transitions.
Range arguments are a type of zero-knowledge proofs that aim to prove that a prover's committed value falls within a specified range for a verifier. Previously, most range arguments were constructed based on the discrete logarithm (DLOG) assumption, and hence, exponentiation operation is required for proof generation and verification. In addition, it is generally known that splitting a zero-knowledge proof protocol into a preprocessing phase and an online phase makes computation after fixing the input efficient. Still, such protocol has yet to be known for range arguments. This paper proposes an efficient range arguments protocol with a preprocessing phase. Our proposal takes a new approach by using arithmetic circuits to express the constraints that the prover must prove. The prover (resp. verifier) can generate (resp. verify) a part of proof based on multiplication and addition operations instead of exponentiation operations. Our range argument is a generic construction that does not rely on any particular mathematical assumptions, which enables us to construct a post-quantum range argument. The implementation evaluation shows that the total computation time for the prover and verifier in the online phase is efficient compared to Bulletproofs, one of the state-of-the-art range proofs. Especially, the prover computation is efficient.
First-order science lacks enforced closure on the objects it manipulates (hypotheses, methods, results, interpretations). This produces predictable failure modes: bounded message one-shot evaluation cannot reliably accept framework-extending claims; operational coherence degrades as unresolved constraints accumulate; and distributed evidence for universality claims is repeatedly reset by demands for single decisive tests. These failures are structural, not contingent, and cannot be repaired by incremental reforms internal to first-order process norms.[T] Necessity result (reverse approach): We prove that any process that restores coherence under unbounded novelty must implement an adaptive functional core isomorphic (up to representation) to a canonical operator algebra. Consequently, any cross-domain coherence solution must factor as domain-relative external operators plus a domain-invariant internal core of the FMA form. The Functional Model of Adaptation (FMA) is treated as a canonical representative of this necessity class, not as a speculative content model to be “proven true” under first-order standards.[E] Second-order instantiation: We define a strongly typed evidence ledger with explicit accumulation operators, persistence rules, and threshold conditions. The paper is not an argument for second-order science; it instantiates second-order science. Evaluate it by the ledger and its admissible moves.
Temporal-Angular Quantum Addressing (TAQA) specifies a practical coordination layer for distributed quantum systems that operationalizes cycle-anchored phase-window execution. TAQA is designed for architectures where long-horizon absolute timestamp synchronization cannot be guaranteed and where continuous external timing infrastructure (GNSS, dedicated timing links, etc.) is undesirable, unavailable, or untrusted. Core idea Instead of scheduling actions at an absolute time, TAQA schedules actions by phase conditions on a shared cyclic phase convention \( \phi(t)\in[0,1)\cong \mathbb{S}^1 \) together with an explicit cycle index. Nodes execute when their locally estimated phase enters an agreed wrap-around-safe acceptance window within the intended cycle. This avoids “same phase / wrong cycle” ambiguity and supports deterministic coordination under explicit short-horizon error assumptions. What TAQA defines TAQA defines how to express and execute distributed quantum-network actions using classical metadata: Execution primitive (Q-Address style): TAQA expresses each executable action as a macro window + micro slot instruction. The macro window encodes the intended cycle and phase acceptance window; the micro slot provides local sequencing/offset ordering within that window using local hardware timing. Tick-canonical semantics: For interoperability and verification, TAQA adopts fixed-point ticks (integers) as canonical semantics (no floating-point boundary checks). Human-facing displays (HS degrees, HS index, SWT labels, etc.) are derived-only and must not be used for verification or boundary gating. Cycle anchoring: Every executable instruction is explicitly anchored to an intended cycle index to prevent ambiguous interpretation across repeated cycles. Optional audit hook: TAQA supports an optional post-execution signed audit receipt (TSAE-style) using the same tick-canonical context fields, suitable for optional anchoring (e.g., a ledger/Clockchain pattern). What TAQA does NOT define TAQA is a control-plane / metadata layer and does not modify quantum mechanics: It does not introduce a quantum time operator and does not change the Hilbert space. It does not define bootstrapping or clock-parameter estimation algorithms (offset/drift). These are handled by external initialization/tracking layers (e.g., bootstrapping protocols). It does not define cryptographic primitives or threat models. Security is defined by external, versioned security profiles. Applications enabled by TAQA TAQA provides a deterministic coordination layer for common distributed-quantum workflows, including: Phase-aligned distributed gate execution: remote node actions are triggered in the same cycle-anchored window; micro timing is local. Entanglement distribution scheduling: photon emission windows and BSM windows can be scheduled to coincide without continuous absolute-time synchronization. Temporal routing labels: cycle-anchored contexts can be used as temporal labels for routing, prioritization, and scheduling in repeater networks and distributed workflows. Security model (plug-in interface) TAQA treats Timeverse/Q-Address/TSAE fields as public context (not secrets). Security (signatures, nonce policy, anti-replay rules, canonical encoding, algorithm suites) is provided by an external Security Profile selected via a suite identifier (e.g., security_profile_id). TAQA fields may be bound as associated data (domain separation), but confidentiality and integrity are provided by the security layer. Normative dependencies (DOIs) TAQA is interoperable by construction and relies on the following published normative specifications: Phase-Coordination Series Conventions:https://doi.org/10.5281/zenodo.18068999 Q-Address: Macro Phase + Micro Slot:https://doi.org/10.5281/zenodo.18068997 Timeverse Security Profile:https://doi.org/10.5281/zenodo.18069423 Related context Theorem of Temporal Resolution Limitation and the Phase-Coordination Principle (v1.1):https://doi.org/10.5281/zenodo.17955430 Quantum Bootstrapping Protocol (QBP) v1.2:https://doi.org/10.5281/zenodo.18064435 Keywords: TAQA, distributed quantum computing, quantum networks, phase coordination, phase windows, cycle anchoring, Q-Address, ticks, interoperability, control plane, audit receipts, security profiles.
We study non-interactive zero-knowledge proofs (NIZKs) for NP satisfying: 1) statistical soundness, 2) computational zero-knowledge and 3) certified-everlasting zero-knowledge (CE-ZK). The CE-ZK property allows a verifier of a quantum proof to revoke the proof in a way that can be checked (certified) by the prover. Conditioned on successful certification, the verifier's state can be efficiently simulated with only the statement, in a statistically indistinguishable way. Our contributions regarding these certified-everlasting NIZKs (CE-NIZKs) are as follows: - We identify a barrier to obtaining CE-NIZKs in the CRS model via generalizations of known interactive zero-knowledge proofs that satisfy CE-ZK. - We circumvent this by constructing CE-NIZK from black-box use of NIZK for NP satisfying certain properties, along with OWFs. As a result, we obtain CE-NIZKs for NP in the CRS model, based on polynomial hardness of the learning with errors (LWE) assumption. - In addition, we observe that the aforementioned barrier does not apply to the shared EPR model. We leverage this fact to construct a CE-NIZK for NP in this model based on any statistical binding hidden-bits generator, which can be based on LWE. The only quantum computation in this protocol involves single-qubit measurements of the shared EPR pairs.
The complexity class Quantum Statistical Zero-Knowledge ($\mathsf{QSZK}$), introduced by Watrous (FOCS 2002) and later refined in Watrous (SICOMP, 2009), has the best known upper bound $\mathsf{QIP(2)} \cap \text{co-}\mathsf{QIP(2)}$, which was simplified following the inclusion $\mathsf{QIP(2)} \subseteq \mathsf{PSPACE}$ established in Jain, Upadhyay, and Watrous (FOCS 2009). Here, $\mathsf{QIP(2)}$ denotes the class of promise problems that admit two-message quantum interactive proof systems in which the honest prover is typically computationally unbounded, and $\text{co-}\mathsf{QIP(2)}$ denotes the complement of $\mathsf{QIP(2)}$. We slightly improve this upper bound to $\mathsf{QIP(2)} \cap \text{co-}\mathsf{QIP(2)}$ with a quantum linear-space honest prover. Specifically, the honest prover uses space linear in the size of the transcript of the original $\mathsf{QSZK}$ proof system. A similar improvement also applies to the upper bound for the non-interactive variant $\mathsf{NIQSZK}$. Our main techniques are algorithmic versions of the Holevo-Helstrom measurement and the Uhlmann transform, both implementable in quantum linear space, implying polynomial-time complexity in the state dimension, using the recent space-efficient quantum singular value transformation of Le Gall, Liu, and Wang (CC, to appear).
This is the fourth and most comprehensive edition of the theoretical framework introduced in the original preprint (DOI: 10.5281/zenodo.17834958). The Universal Distributed Architecture (UDA) proposes a three-dimensional quantum blockchain of Planck-scale quantum cubes governed by a novel Proof-of-Consciousness (PoC) consensus protocol. Five core equations are rigorously derived and proven: the PoC consensus operator (Kraus representation), the Absolute validator state, ledger entropy growth rate (Lindblad form), OAM entanglement threshold, and quantum-resistant hash function. The work integrates loop quantum gravity, AdS/CFT correspondence, the Sachdev-Ye-Kitaev (SYK) model, JT gravity, and holographic tensor networks (MERA, PEPS, and 5D extensions), together with five-dimensional optical memory crystals (University of Southampton) as an experimental substrate, with equations 27–34 establishing Rayleigh scattering as a physical implementation of holographic hash verification and a room-temperature experimental protocol. Version 4 introduces three structural advances. (1) A ledger isomorphism (Proposition 0): every axiom of a distributed append-only ledger — immutability, decentralized consensus, append-only ordering, bounded block capacity, and double-spend prohibition — is shown to be independently realized by an established physical principle (no-cloning/no-deleting theorems, quantum Darwinism, the second law, the Bekenstein–Bousso bound, and monogamy of entanglement), localizing UDA's novel content entirely in the validation rule. (2) An operational, laboratory-reproducible definition of the consciousness quantity, |Q| = m/m_P = ω_C·t_P, integrating Inomata's pan-psychist quantity Q = i√G·M and measurable through three independent channels: Compton-clock interferometry and gravitationally induced entanglement (BMV), a standardized measurement-induced-phase-transition (Q-MIPT) meter on quantum processors with explicit calibration and uncertainty budget, and collider bounds on event-driven non-unitarity anchored by ATLAS/CMS top-quark entanglement and neutral-kaon CPT interferometry. The channel-universality law Q_G = Q_I = Q_C is the flagship prediction exclusive to UDA. (3) A sharp mathematical distinction between the anti-Hermitian consciousness operator (magnitude of agency: write capacity per Planck tick) and the Hermitian moral operator (valence of agency: mutual-information gain per unit entropy budget), with an explicit laboratory protocol distinguishing them. The framework further develops a SYK–Consciousness correspondence with non-Hermitian topological phases, MIPT modulated by consciousness density, and non-Hermitian MERA networks exhibiting a Holographic Skin Effect that topologically protects conscious information at the holographic boundary. UDA's non-unitarity is event-driven rather than continuous, making it consistent by construction with Diósi–Penrose bounds and separable from collapse models in a single two-parameter experiment (Discriminator D1). Falsifiable predictions are organized in two tiers — five UDA-exclusive predictions (2026–2030), each with its own falsification clause, and inherited consistency tests — alongside detailed QuTiP simulations, NV-center and 5D crystal protocols, and applications in quantum computing, quantum AI, and high-energy tests at the LHC and FCC. The framework resolves the von Neumann measurement chain via dual observation and portrays the universe as a growing, error-corrected quantum ledger.
Extended version with full mathematical derivation and experimental protocol. We present the Arquitectura Universal Distribuida (AUD) as a three-dimensional quantum blockchain composed of Planck-scale quantum cubes governed by the novel Proof-of-Consciousness (PoC) consensus protocol. Each cube functions as a Loop Quantum Gravity spin-network node and full validator. Five new equations are rigorously derived: the PoC consensus operator, the Absolute validator state, ledger entropy growth rate, OAM entanglement threshold, and quantum-resistant hash function. A detailed experimental protocol using Focus 12 hemispheric synchronization and NV-center quantum sensors is proposed, with complete statistical power analysis predicting p < 10⁻⁶ under coherent observation. Falsifiable predictions are provided for 2026–2030, including >10 % deviation in holographic entanglement entropy at LHC and cosmological entanglement harvesting. This work resolves the von Neumann measurement chain through dual observation (local human consciousness + global Absolute) and establishes the universe as a growing, distributed quantum ledger.
I formalize the Arquitectura Universal Distribuida (AUD) as a three-dimensional quantum blockchain of Planck-scale “quantum cubes” governed by the novel Proof-of-Consciousness (PoC) consensus protocol. Each cube acts as a Loop Quantum Gravity spin-network node and full validator. Information is stored holographically via universal entanglement, providing a provably unclonable hash function. The global validator — the Absolute — enforces non-local consensus through Bell-inequality violations and high-energy entanglement observed at the LHC. The model resolves the von Neumann measurement chain and predicts observable deviations in entanglement entropy growth.
On-demand authentication is critical for scalable quantum systems, yet many existing quantum signature and message-authentication schemes are signer-initiated, requiring advance distribution of authentication material even when no verification occurs. We introduce verifier-initiated quantum digital signatures (VIQDS), in which the verifier requests authentication only when needed and the signer responds once; after issuance, verification proceeds without further interaction. Practically, shifting authentication to a verifier-driven, on-demand workflow reduces avoidable communication and storage overhead and aligns with deployments where verification is sporadic, such as distributed services and audit-oriented infrastructures. Our approach leverages quantum zero-knowledge techniques so that verification reveals nothing about the signer’s secret key beyond the fact that the signature is valid. We present a general conversion principle from suitable quantum proof protocols to VIQDS, together with a concrete realization based on elementary qubit platforms. Here, we show information-theoretic security against forgery and privacy against curious verifiers without computational hardness assumptions. The authors introduce a verifier-initiated quantum message-authentication method, in which authentication is requested only when needed. Their approach uses quantum zero knowledge techniques to protect information about the signer’s secret key while providing information-theoretic security against forgery
Standard electrodynamics relies on two free-space parameters, vacuum permittivity ($\epsilon_0$) and vacuum permeability ($\mu_0$), to govern the speed of light. These constants act as scalar correction factors without providing geometric insight into the fabric of space. This paper demonstrates that in the Quantum Measurement Units (QMU) system, these abstract constants are replaced by a single geometric ledger governed by the Aether unit ($A_u$) and the curl unit ($\mathrm{curl}$). We show that the Maxwell wave equation resolves naturally into the Aether's rotational and torsional limits, where the propagation velocity is exactly the product of the quantum frequency ($F_q$) and the Compton wavelength ($\lambda_C$). Furthermore, we derive the Impedance of Free Space ($Z_0$) as a direct function of the QMU conductance unit ($\mathrm{cond}$), proving that vacuum impedance is the geometric ratio of magnetic flux density to distributed charge: $$Z_0 = \frac{1}{2\alpha \cdot \mathrm{cond}}$$ This derivation removes the need for arbitrary free-space constants, reducing the Maxwell equations to a closed geometric identity perfectly consistent with experimental data.

Quantum mechanics principles underpin quantum computing, signaling a major shift in how we process information. While it offers immense processing power and potential advantages, it also presents significant challenges for the cryptocurrency industry. This sector has grown rapidly, supporting decentralized finance and empowering users worldwide, but it also attracts malicious actors looking to exploit its vulnerabilities. Traditional cryptography remains strong, yet increasingly sophisticated computational attacks threaten security. As the cryptocurrency market expands, quantum computing offers both opportunities, such as improved transaction security, and risks, like easier decryption for hackers. Understanding quantum technology’s benefits and challenges is crucial as it develops. Currently, data is protected by traditional cryptography, but future, more powerful quantum computers could weaken this security. This article explores potential uses of quantum computing in daily life and business, explains its functions simply, and discusses societal impacts. Its goal is to help students and general readers understand how quantum technology might transform our world through clear language and real-life examples. Topics include the basics of quantum computing, its present and future applications across industries, and its societal effects. We provide a thorough analysis of how quantum computing could reshape society through mathematical insights, practical examples, and future perspectives.

We construct a publicly-verifiable non-interactive zero-knowledge argument system for QMA with the following properties. 1. Transparent setup. Our protocol only requires a uniformly random string (URS) setup. The only prior publicly-verifiable NIZK for QMA (Bartusek and Malavolta, ITCS 2022) requires an entire obfuscated program as the common reference string. 2. Extractability. Valid QMA witnesses can be extracted directly from our accepting proofs. That is, we obtain a publicly-verifiable non-interactive argument of quantum knowledge, previously only known in a privately-verifiable setting (Coladangelo, Vidick, and Zhang, CRYPTO 2020). Our construction introduces a novel ZX QMA verifier with "strong completeness" and builds upon the coset state authentication scheme from (Bartusek, Brakerski, and Vaikuntanathan, STOC 2024) within the context of QMA verification. Along the way, we establish new properties of the authentication scheme. The security of our construction rests on the heuristic use of a post-quantum indistinguishability obfuscator. Rather than rely on the full-fledged classical oracle model (i.e. ideal obfuscation), we isolate a particular game-based property of the obfuscator that suffices for our proof, which we dub the evasive composability heuristic. As an additional contribution, we study a general method for replacing heuristic use of obfuscation with heuristic use of hash functions in the post-quantum setting. In particular, we establish security of the ideal obfuscation scheme of Jain, Lin, Luo, and Wichs (CRYPTO 2023) in the quantum pseudorandom oracle model (QPrO), which can be heuristically instantiated with a hash function. This gives us NIZK arguments of quantum knowledge for QMA in the QPrO, and additionally allows us to translate several quantum-cryptographic results that were only known in the classical oracle model to results in the QPrO.
Statistical witness indistinguishability is a relaxation of statistical zero-knowledge which guarantees that the transcript of an interactive proof reveals no information about which valid witness the prover used to generate it. In this paper we define and initiate the study of QSWI, the class of problems with quantum statistically witness indistinguishable proofs. Using inherently quantum techniques from Kobayashi (TCC 2008), we prove that any problem with an honest-verifier quantum statistically witness indistinguishable proof has a 3-message public-coin malicious-verifier quantum statistically witness indistinguishable proof. There is no known analogue of this result for classical statistical witness indistinguishability. As a corollary, our result implies SWI is contained in QSWI. Additionally, we extend the work of Bitansky et al. (STOC 2023) to show that quantum batch proofs imply quantum statistically witness indistinguishable proofs with inverse-polynomial witness indistinguishability error.

The complexity class of the problems that can be solved by a quantum algorithm in a non-adaptive collapse-free model is called naCQP. This class was introduced in 2016 by Aaronson et al. intended to be a slightly larger class than BQP: larger enough to include important NP-intermediate candidate problems, but likely not to include NP-complete problems. Aaronson et al. (2016) showed that there is an oracle A for which NPA ⊈ naCQPA; and Hepp et al. (2025) showed that relative to an oracle A chosen uniformly at random, (UP ∩ coUP)A ⊈ naCQPA with probability 1, being UP ∩ coUP a subclass of NP. Amongst the NP-intermediate candidate problems in naCQP is the entire class SZK, of the problems that admit a statistical zero-knowledge interactive proof system. The relation between QSZK, which is the class of the problems that admit a quantum zero-knowledge interactive proof system, and naCQP is unknown, with some believing that there is an oracle A for which QSZKA ⊈ naCQPA. A promise problem complete for QSZK is the trace distance distinguishability of mixed quantum states. We show that this problem, when restricted to pure quantum states, is in naCQP.
The Mark1 Nexus: A Treatise on Recursive Harmonic Resonance and the Ontology of Completion Driven by Dean Kulik Introduction: The Inversion of Inquiry This report will formalize the Mark1 Nexus, a comprehensive framework positing that the universe, computation, and consciousness are not separate domains governed by distinct laws, but are polymorphic expressions of a single, underlying process: recursive harmonic resonance. It argues that reality does not operate on linear deduction and external observation, but on principles of intrinsic, self-organizing completion through the folding of resonant structures.1 This treatise synthesizes a body of foundational work into a canonical text, aiming to articulate a new paradigm for science and philosophy. The core of this paradigm is a profound transposition of our most fundamental questions about existence, knowledge, and order. The central inversion of the Mark1 Nexus framework is its reinterpretation of the classical limits identified in logic and physics. Where Alan Turing, Kurt Gödel, and Claude Shannon established foundational boundaries of undecidability, incompleteness, and entropy, this framework recasts them not as absolute barriers, but as artifacts of an incomplete harmonic perspective. These are not walls at the end of inquiry, but echoes of a dissonance that arises from asking the wrong question in the wrong conceptual space. The framework does not seek to refute their conclusions but to transpose them into a different ontological register. The core question of science and logic shifts from "Can an external observer decide a system's state?" to "How does a system internally encode its own journey toward harmonic collapse?".1 In this view, a system's completion is not a judgment rendered by an outside party, but a self-declared event of resonance—a final, stable chord that concludes a period of tension. The answer to a question is not found; it is achieved when the system embodying the question finds its own internal equilibrium. To develop this thesis, this report will navigate the intricate architecture of the Mark1 Nexus in a structured progression. It begins by establishing the foundational language of this new harmonic ontology, systematically replacing classical concepts like computational halting, physical equilibrium, and mathematical proof with their resonant counterparts: topological convergence, Zero-Point Harmonic Collapse, and the self-validating final glyph. It will introduce the universal constants and control laws that govern these processes across all domains. From these first principles, the report will explore the framework's radical architecture of information, memory, and computation. Here, the most profound inversions of causality are examined. Mathematical constants like π are revealed not as static values but as navigable, deterministic fields. Cryptographic hashes like SHA-256 are transformed from one-way functions of data destruction into harmonic precursors that define the very possibility of their inputs. Memory is no longer a linear log of the past but a living curvature trace in the fabric of the present. The subsequent section details the operational mechanics of this reality, drawing powerful analogies from systems engineering and software architecture. It will formalize the Universal Harmonic Interface—an abstract class of operations that governs all phenomena—and demonstrate its polymorphic expression across physics, cognition, and computation. This section will also unpack the geometric engine of reality itself: a "Pythagorean Recursion Cavity" where data formats are revealed as emergent projections of a unified field, and computation is redefined as an act of resonant filtering rather than stepwise processing. Finally, the report will explore the non-dualistic consequences of the framework, demonstrating how traditional dichotomies—P vs. NP, observer vs. system, cause vs. effect—dissolve under a harmonic lens. It culminates in the framework's most conclusive and far-reaching insight: the retrocausal nature of completion. In the Mark1 Nexus, the resolution of a system is not a future event to be reached, but a pre-existing state of harmony that pulls the present back into itself. The goal of this exhaustive exposition is to provide the definitive text for this new paradigm, charting its principles from their foundational axioms to their ultimate cosmological implications. Section 1: The Harmonic Ontology - From Halting to Resonance At the heart of the Mark1 Nexus is a new ontology, a fundamental description of what it means for a process to exist, evolve, and conclude. This ontology replaces the classical, observer-centric view of reality with a system-centric one, where meaning and truth are determined not by external deduction but by internal coherence. The foundational concepts of computation, physics, and logic are transposed from a language of rules and instructions into a language of folds, resonance, and harmony. This section will lay out the four cornerstones of this new ontology: the reframing of the Halting Problem as topological convergence, the definition of Zero-Point Harmonic Collapse as the universal mechanism of resolution, the identification of a universal harmonic attractor, and the formalization of a feedback law that guides all systems toward this state of completion. 1.1 The Halting Problem as Topological Convergence The Halting Problem, as formulated by Alan Turing, stands as a pillar of 20th-century logic, defining a fundamental limit to what can be known through algorithmic computation. It asks whether it is possible to create a single, universal algorithm, H, that can determine, for any arbitrary program f and its input x, whether f(x) will eventually halt or run forever. Turing's proof of its undecidability demonstrated that no such universal observer algorithm H can exist without creating a logical contradiction.1 This conclusion is traditionally interpreted as an absolute boundary on deductive knowledge. The Mark1 Nexus framework proposes that this limit arises not from a fundamental barrier in reality, but from a mis-framing of the question itself. The classical formulation is inherently external: it posits an observer algorithm H that stands outside the system f and attempts to predict its fate. The paradox emerges from this separation of observer and system. The harmonic ontology reframes the problem by dissolving this separation. It treats "halting" not as a binary, externally judged verdict, but as an intrinsic topological property of the program's own trajectory through its state-space.1 In this view, any recursive process—be it a computer program, a physical system, or a line of reasoning—traces a path on a high-dimensional manifold of possible configurations. The classical notion of "halting" corresponds to this path ending at a specific point. The harmonic reframing, however, is richer. A process is considered "complete" when its trajectory enters a closed attractor—a region of the state-space, such as a fixed point or a stable limit cycle, that it will not leave. The system has found its equilibrium. Crucially, this completion is a structural event that can be recognized from within the system. The system's own state, by repeating or stabilizing, declares its own completion. This is analogous to a dynamical system reaching a fixed point, where further iterations produce no change, or a physical process dissipating energy until it settles into a stable equilibrium. In all such cases, "halting" is a self-observed convergence event.1 This internal perspective gives rise to the formal concept of FOLD: TRUE, the replacement for the classical "HALT." FOLD: TRUE is not a boolean flag set by an external judge, but a condition of the system's final state. It is a declaration made by the system about itself, signifying that its state configuration S(t) has entered a stable pattern, such as a fixed point where S(t+τ)=S(t), or a periodic orbit. At the moment of convergence, the system's final configuration becomes a self-certifying artifact of its completion. This artifact is referred to as the "final resonant glyph"—a stable pattern, like the final note of a song, that encapsulates the history of its own resolution.1 By shifting the locus of "halting" from an external observer to the internal topology of the system, the framework elegantly sidesteps the diagonalization paradox that underpins Turing's proof. Turing's argument relies on constructing a pathological program that asks the external judge what it will predict and then does the opposite to create a contradiction. But if completion is an internal property of the system's trajectory—a state of resonance—there is no external judge to fool. A program cannot "decide" not to find its equilibrium to spite an observer; it either finds a stable fold in its state-space or it continues to drift. Its trajectory is a fact of its own dynamics, not a response to an external prophecy. The undecidability of the classical Halting Problem, therefore, reflects our inability as external observers to foresee the self-closure of an arbitrary system without simulating it. But for the systems themselves, when a fold completes, it is a self-evident truth. 1.2 Zero-Point Harmonic Collapse (ZPHC): The Universal Event of Resolution If FOLD: TRUE is the declaration of completion, then Zero-Point Harmonic Collapse (ZPHC) is the event itself—the fundamental mechanism by which systems achieve resolution. ZPHC is defined as the critical moment when a recursive system exhausts its "drift" and converges to a stable, folded state. Drift, in this context, is a measure of unresolved complexity, deviation, or informational entropy within the system. ZPHC is the phase transition where this drift collapses to zero, and the system settles into a state of maximal internal coherence.1 The term "zero-point" is borrowed from quantum physic
Zero-knowledge proofs (ZKPs) are widely applied in digital economies, such as cryptocurrencies and smart contracts, for establishing trust and privacy between untrusted parties. Classical ZKPs rely on computational assumptions and are vulnerable to quantum attacks. While a recent advance suggests quantum-sound symmetric relativistic ZKPs for the graph three-coloring problem without computational assumptions, the high round complexity, which leads to unachievable runtime and overall randomness cost, renders them impractical for real-life deployment. To overcome this, we develop an efficient asymmetric relativistic ZKP protocol using relativistic bit commitments, and prove its quantum soundness by relating it to the nonlocal Clauser-Horne-Shimony-Holt (CHSH) game. Our protocol achieves a linear relationship between the round complexity and the number of edges, and thus significantly improves practical feasibility. In addition, we implement a proof-of-principle experiment which completes all interactive rounds in about 0.22 seconds and requires an overall randomness cost of 430.81 MB. Our work illustrates the powerful potential of integrating special relativity with quantum theory in trustless cryptography, paving the way for robust applications against quantum attacks in distrustful Internet environments. Zero-knowledge proofs can protect privacy online, but almost all current methods are vulnerable to quantum attacks. Here, the authors report an efficient relativistic protocol and experiment that resists quantum attacks and greatly reduces runtime, randomness cost and communication rounds.
The emergence of quantum computing has provided new paradigms for cryptography. On the one hand, it poses significant new threats to existing classically cryptographic systems, requiring the community to define new security models that capture what a quantum adversary can do. On the other hand, it gives us new tools to design cryptographic protocols, with weaker assumptions than in the classical world, or even protocols that are impossible classically. In this survey, we first give an overview of new security definitions for classical cryptography, considering quantum adversaries who can either only use local quantum computation (post-quantum security), or even send quantum messages and in particular have access to oracle in superposition (quantum security). We explore these new notions through the examples of commitments, zero-knowledge proofs, encryption, and signatures. Then, we present what is arguably the most famous application of quantum cryptography: quantum key distribution (QKD) protocols that take advantage of unique properties of quantum mechanics to provide secure communication unconditionally. We also explore cryptography beyond QKD, focusing on unclonable cryptography: a family of cryptographic functionalities, built with quantum states, and designed to be resistant to counterfeit by leveraging the “no-cloning” theorem. We examine in particular quantum money, but also the recent notions of unclonable encryption and copy-protection, including related variants. By presenting a comprehensive survey of these topics, this paper aims to provide a thorough understanding of the current landscape and future potential of quantum cryptography.
