Three problems that are out of reach for conventional computers have been cracked by quantum computers and show how important ...

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 ...

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

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 ...

If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too ...

Michael Osei is interested in whether a quantum computer is fast but also does it produce reliable, high-quality, ...

Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality.

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

Researchers unveiled a new technique that validates quantum computer results—especially those from GBS devices—in minutes instead of millennia. Their findings expose unexpected errors in a landmark ...

CMOS-built optical phase modulators shrink laser control hardware and power use for trapped atom quantum computers, enabling larger stable qubit arrays at work. (Nanowerk News) Researchers have made a ...

A Chinese technology company called SpinQ has begun selling desktop quantum computers that run at room temperature, marking the first time buyers can purchase such hardware without the extreme cooling ...

Scientists have created the first quantum material that can sort and transport different quantum states of light at room ...
