Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ever ‘superposition’ — a quantum state in which an object exists in a haze of possible locations at once. A team ...
