Quantum Chain of Things (QCoT): A New Paradigm for Integrating Quantum Computing, Blockchain, and Internet of Things

Abstract

Recently, Internet of Things (IoT) and Blockchain (BC) are coupled to present smart and secure applications. Quantum Computing (QC) is a new paradigm that imposes itself as a main technology in the near future, especially in the 6G era, due to its powerful computations. As a result, immigration of the IoT and BC to the QC has to be studied and prepared. This paper provides a brief review of relevant recent work to identify opportunities for optimal integration. Besides, a new paradigm called Quantum Chain of Things (QCoT) is proposed and its perspective architecture is presented and verified into two parts: (a) BC-IoT using Arduino, and (b) QC-IoT using IBM Qiskit simulator. Finally, presented knowledge such as current challenges, threads, and integration opportunities could help researchers to investigate new trends and future directions.
