In the global race to build bigger and better quantum computers, researchers have taken a step forward. A new machine called ...

Quantum computers promise to outperform today's traditional computers in many areas of science, including chemistry, physics, and cryptography, but proving they will be superior has been challenging.

Aaron Lauda has been exploring an area of mathematics that most physicists have seen little use for, wondering if it might have practical applications. In a twist even he didn’t expect, it turns out ...
