But quantum computing uses “quantum bits,” also known as “qubits.” Instead of being either zero or one, qubits can behave like zero or one simultaneously and exist in states between zero and one, ...

Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward—is one image that helps us picture how a quantum computer handles ...

Alexa von Tobel is fully aware that her big bet on quantum computing may never pay off. “The risk of being too early is a real risk,” she says. She’s speaking to me via Zoom from the New York City ...

D-Wave, IonQ, and Rigetti use different approaches to build quantum computers. All three companies are unprofitable but are generating sales from their quantum systems. The odds are stacked against ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...
