"A Quantum Computing Future Is Unlikely, Due to Random Hardware Errors"

Google announced that it had achieved quantum supremacy by performing a specific quantum computation at a greater speed than the best classical computers. IBM contested Google's claim of quantum supremacy, expressing that it had already made this breakthrough with its classical supercomputer having the capability to perform the computation almost at the same speed as Google's latest quantum processor, but with a higher degree of accuracy. However, there are still doubts about quantum computing as Michel Dyakonov, a theoretical physicist at the University of Montpellier in France has stated reasons as to why practical quantum supercomputers will never be built. Random errors, which are unavoidable in any physical system, make the future of quantum computing unlikely. This article continues to discuss what a quantum computer is, the need for noise and error correction in quantum computing, as well as quantum cryptography.
