Austrian experimental physics
Anton Zeilinger
1945
Austrian experimentalist who pioneered multi-particle entanglement, quantum teleportation, and entanglement-based quantum cryptography, and pushed Bell tests to ever longer distances and tighter loopholes. His group also demonstrated matter-wave interference with large molecules such as C60. He shared the 2022 Nobel Prize in Physics with Alain Aspect and John Clauser.
