A Quantum Computing Future Is Unlikely https://www.govtech.com/products/A-Quantum-Computing-Future-Is-Unlikely-Due-to-Random-Hardware-Errors.html
Google claims quantum supremacy – IBM says not so fast. One researcher explains why he doesn't see quantum computers outpacing classical computers any time soon ... and maybe not ever.
"As someone who has worked on quantum computing for many years, I believe that due to the inevitability of random errors in the hardware, useful quantum computers are unlikely to ever be built."
