For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

A quantum computer made of charged atoms can catch its own errors when performing any operation – a meaningful step towards more reliable and practical quantum computers. Conventional computers ...

Google claimed Wednesday it has managed to cut calculation time to 200 seconds from what it says would take a traditional computer 10,000 years to complete. Working with physicists at the University ...

Researchers at the University of Bristol in the UK have made a prototype optical quantum computer chip and used it to perform a mathematical calculation for the first time. The device consists of tiny ...

Four years ago, physicists at Google claimed their quantum computer could outperform classical machines — although only at a niche calculation with no practical applications. Now their counterparts at ...
