Physicists have replicated the famous Schrödinger's cat experiment at hotter temperatures than ever before. The breakthrough is a small but significant step toward quantum computers that can work ...

Schrödinger's cat states exist in two distinct quantum states simultaneously and take their name from Erwin Schrödinger's famous thought experiment of a cat that is both simultaneously alive and dead.

Devised in 1935 by the Austrian physicist Erwin Schrödinger, this thought experiment was designed to shine a spotlight on the difficulty with interpreting quantum theory. Quantum theory is very ...

A fault-tolerant quantum computer could be here by 2030, thanks to an invention called the "cat qubit," named after the famous Schrödinger's cat thought experiment, in which a cat locked in a box ...
