When quantum computers become commonplace, current cryptographic systems will become obsolete. Scientists are racing to get ahead of the problem and keep our data secure.

Quantum computers have long promised to surpass their classical counterparts, but concretely demonstrating this advantage remains a major challenge. A team of researchers has just taken a significant ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

The laws of quantum mechanics make it impossible to copy quantum information, but that doesn’t mean quantum computers are unhackable. Two independent teams of researchers have now devised methods for ...

It would take normal computer 10,000 years to solve the same problem. Google announced Wednesday it designed a machine that would take only 200 seconds to solve a problem that the world's fastest ...

STOCKHOLM/COPENHAGEN, July 17 (Reuters) - The Novo Nordisk Foundation and Denmark's state-owned credit fund said on Thursday they will invest in what they say will be the world's most powerful quantum ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

Some quantum computing stocks delivered gains of more than 1,000% last year. The technology has game-changing potential, and quantum companies may thrive if the economic backdrop is supportive.
