Alain Aspect, John F. Clauser and Anton Zeilinger won the 2022 Nobel Prize in Physics for their work using entangled photons to test the quantum foundations of reality
This year’s Nobel Prize in Physics was awarded in equal parts to Alain Aspect of the University of Paris-Saclay, John F. Clauser of J.F. Clauser & Associates, and Anton Zeilinger of the University of Vienna, for their pathfinding work in quantum mechanics and quantum information science.
Expanding on a concept proposed some three decades prior by Einstein, Boris Podolsky and Nathan Rosen, Bell in 1964 showed that if hidden variables existed, their presence could be experimentally inferred through careful measurements of multiple pairs of entangled particles.
Zeilinger and his group greatly expanded the use and study of entangled quantum states. They became the first researchers to demonstrate a behavior called quantum teleportation, which uses entanglement to allow quantum states to be moved from one particle to another across arbitrary distances.
"The work of Aspect, Clauser and Zeilinger provides the practical theoretical method and conclusive experimental measurements that underline the distinction between the quantum and classical worlds, showing that quantum objects can be related through entanglement in a way that is not possible with classical objects,” says Andrew Cleland, a quantum physicist at the University of Chicago. “Their work forms the fundamental basis for quantum computation and quantum communication.
