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

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 ...

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

For the first time, a quantum computer has successfully measured pairing correlations (quantum signals that show electrons teaming up in pairs), which is essential to helping scientists find one of ...

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

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 ...

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 ...

With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing ...

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.

We may never beam ourselves off the planet. But quantum teleportation is poised to bring about a new era of computing—and revolutionize our understanding of the subatomic world. This composite photo ...
