Researchers have achieved a major milestone in quantum computing after successfully generating “truly random” numbers using the next-generation machines. Quantum computers hold the potential to be ...

A team that included researchers at a US bank says it has created a protocol that can generate certified truly random numbers, opening the possibility that current generation quantum computers can be ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...

Peter Shor didn’t set out to break the internet. But an algorithm he developed in the mid-1990s threatened to do just that. In a landmark paper, Shor showed how a hypothetical computer that exploited ...
