A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

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 ...

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 ...

Quantum physicist Vlatko Vedral proposes a radical new vision of reality, one in which observers don’t exist, there are no particles and there is no space or time. Instead, for Vedral, quantum numbers ...

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 information systems, systems that process, store or transmit information leveraging quantum mechanical effects, could, in principle, outperform classical systems in some optimization, ...
