In the fast-evolving world of quantum computing, one of the biggest hurdles isn't how fast calculations can be done—it's how long you can hold onto the delicate quantum information in the first place.

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum ...

The U.S. and China are racing to develop computers based on the properties of quantum physics – with implications for science ...

A quiet revolution is taking shape in the world of physics, and it doesn't rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Researchers have developed an ultra-thin drumhead-like membrane that lets sound signals, or phonons, travel through it with astonishingly low loss, better than even electronic circuits. These ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...
