Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered ...

Wrapping your head around quantum physics is tricky, no matter how well-educated you are -- if it were easy, there wouldn't be problems making quantum computers. However, researchers at the National ...

A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to ...

Quantum computing is widely believed to be a revolutionary new technology. In fact, it is a double-edged sword. If efficient ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Researchers at the University of Southern California (USC) in the US turned to an often overlooked particle for storing and processing quantum information to overcome the fragility of quantum ...

Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them ...
