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 new type of quantum computer has proven that it can reign supreme, too. “This is the first independent confirmation of Google’s claim that you really can achieve quantum supremacy,” says theoretical ...

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 ...

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 ...
