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 ...

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 ...

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 ...

The approach is known for high accuracy, but scaling it up while preserving that accuracy is technically difficult. Helios uses barium ions in what is called a quantum charge-coupled device, or QCCD, ...

A Chinese technology company called SpinQ has begun selling desktop quantum computers that run at room temperature, marking ...

“However, a quantum computer can only function properly if its qubits are not disturbed too much,” Schützhold emphasizes. Engineers protect qubits by shielding them from electromagnetic radiation and ...

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

Add Yahoo as a preferred source to see more of our stories on Google. New Bedford Science Café will host a discussion on quantum computing from 6 to 8 p.m. Sept. 9. The event will take place at The ...

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.

The new startup raised $300 million co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures.

Chinese quantum scientist Pan Jianwei has become the first scientist from China to win the UNESCO-Russia Mendeleev ...
