IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

A micro-scale quantum heat engine that converts thermal energy to usable work under near-zero temperatures has paved the way ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Nefarious actors are harvesting encrypted data to decrypt it once quantum computing gives them the ability to do so. Identify ...
