Concept and Algorithm of Quantum Computing During Pandemic Situation of COVID-19

We are observing in this pandemic situation of COVID-19 the world in very challenging and to solve this complex problem in quick time. Today, we are facing a difficult complex problem such as Coronavirus. This Coronavirus affects human life. Quantum computing is the only support that can give us quick results by processing the Coronavirus compound at high computation speed. Whatever present circuits in VLSI domain, we cannot perform the high-speed computation and not tackle the complex case as present COVID-19. In this article, we have been discussed about quantum computing era during the pandemic situation of COVID-19. Further, this paper presents fundamental about quantum properties such as superposition, entanglement, and quantum programming tools such as Qiskit (IBM), pyQuil (Google), ProjectQ (ETH), Revkit, and RCvewier +. We have presented quantum circuit and its decomposed circuit of such gates as Toffoli, Fredkin, Peres, and new fault tolerance. In addition, we proposed algorithm as transforming cascade to the quantum circuit which is extended for verification based. All these concepts presented here will be very useful to researcher, academician, and industry person to tackle this pandemic situation of COVID-19. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
