Blockchain-based delegated Quantum Cloud architecture for medical big data security

Abstract

Smart Healthcare systems compromise complex computations such as visualization of molecules, analysis of DNA, and therapy determination. These are considered to be complex problems that today's supercomputers are still facing. On the other hand, Quantum computing promises fast, efficient, and scalable computing resources that are sufficient to compute large and complex operations in exponential time. It is a fact that Quantum computing will adequately innovate the computation perspective. However, it is not a feasible solution yet as it is likely to be rare and highly expensive to produce. This paper presents a Quantum Cloud-as-a-service for an efficient, scalable, and secure solution for complex Smart Healthcare computations. Our novelty resides in the usage of Quantum Terminal Machines (QTM) and Blockchain technology to enhance the feasibility and security of the proposed architecture. Experimental results prove the feasibility of the architecture and the absolute security of the implemented Q-OTP encryption.
