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 ...

Physicists have identified a new superfluid phase in a class of quantum systems that, until recently, looked too unstable and ...

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 ...
