Quantum computing's biggest challenge isn't speed - it's proving results are correct. Here's why verification matters more ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

Three problems that are out of reach for conventional computers have been cracked by quantum computers and show how important ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

Four independent research teams report big advances in devices built with the underestimated quantum bits, including lower ...

The promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware.
