After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is.

IBM and IonQ are both early movers in the nascent market.

At the time, their technique was a fascinating but impractical creation. Forty years later, it is poised to become an ...
