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

Four independent research teams report big advances in devices built with the underestimated quantum bits, including lower ...

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 ...

Mon, June 22, 2026 at 3:09 PM UTC It's hard to know what to make of quantum computers. On the one hand, it may very well be like where AI was five or seven years ago. And, if that's the case, perhaps ...

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.

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

SAN FRANCISCO (Reuters) -IBM announced on Wednesday it has built a new experimental quantum computing chip called Loon that demonstrates it hit a key milestone toward making useful quantum computers ...

Explore the potential of quantum computing and the challenges ahead as researchers strive to overcome noise and errors.

Why pairing quantum processors with classical systems will determine real-world quantum success.

The truth is less dramatic. There are three ways that AI and quantum computers overlap: first, in the problems they try to ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...
