Fully practical quantum computers haven’t arrived yet, but the quantum computing industry is ending the year on an optimistic note. At the Q2B Silicon Valley conference in December, which brings ...

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.

Welcome to another biweekly update on all things quantum computing. This edition covers the next stage of DARPA’s national quantum push, a new high-precision system from Quantinuum, and fresh ...

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

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 ...

Amazon AI executive Peter DeSantis told CNBC that in five-to-seven years, "we're going to start to see the first commercially useful small-scale quantum computers." DeSantis leads a new Amazon ...

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 ...

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 ...

Earlier this year, IBM disclosed that it was nearing $1 billion in cumulative signings related to quantum computing. The tech giant works with hundreds of partners, including established companies, ...

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 ...

Peter DeSantis predicts commercially useful quantum computers will arrive within 5 to 7 years, following a Moore's Law-like growth curve. Google's Quantum AI division is already beating its own ...
