Quantum Computing

Individual atoms trapped by optical “tweezers” are emerging as a promising computational platform

A new algorithm is probably not efficient enough to crack current encryption keys—but that’s no reason for complacency, researchers say

The same physics that makes quantum computers powerful also makes them finicky. New techniques aim to correct errors faster than they can build up

A new magnetic material, just one atom thick, can manipulate electrons’ spin for next-generation data storage

The competition between the U.S. and China over development of quantum technology has implications for both the future of science and the two countries’ political relations

New research shows that there are problems even quantum computers might never be able to solve

One expert warns that the field is overpromising, while another says his firm is on the verge of building “useful” machines

It will bring molecular modeling to a new level of accuracy, reducing researchers’ reliance on serendipity

Let’s take advantage of this early stage of their development to avoid the mistakes of past technological upheavals

Physics is still dominated by men, which means we’re largely missing out on the talents of half the population

The setup of lasers and mirrors effectively “solved” a problem far too complicated for even the largest traditional computer system

A downsized version of the company’s Sycamore chip performed a record-breaking simulation of a chemical reaction
