Chinese researchers have successfully built a silicon quantum chip that can perform error-detecting logical operations, a crucial step towards developing reliable quantum computers.

Chinese researchers have shown that a silicon quantum chip can carry out a full set of error-detecting logical operations – the first time this has been done and a key step towards building reliable quantum computers. The study, published in Nature Nanotechnology on Monday, found the device could process quantum information with built-in error checks – something previously achieved in platforms like superconducting circuits but not with silicon. According to the team from the Shenzhen...
