Schrödinger’s Cat (IMAGE) DOE/Sandia National Laboratories Caption Erwin Schrödinger used the analogy of a cat in a box to illustrate the fragile nature of quantum states, which collapse upon observation. But atoms, like cats, can escape. Researchers at Sandia National Laboratories and the University of New Mexico developed a method to monitor neutral atom qubits in a processor without collapsing their quantum states. Their technique is like placing the box on a scale that shows whether the cat is still inside while keeping it closed.
