Nobel Prize in Physics 2022 awarded to Alain Aspect, John F Clauser & Anton Zeilinger.

  • The Nobel Prize in Physics 2022 has been awarded to Alain Aspect (France), John F Clauser (USA) and Anton Zeilinger (Austria) for their work on quantum mechanics, the Royal Swedish Academy of Sciences announced on 4th October 2022.
  • The 2022 Nobel Prize in Physics is awarded “for experiments with entangled photons, establishing violations of Bell inequalities, and pioneering quantum information science”.

John Clauser

The 2022 Nobel laureate John Clauser created a device that emitted two entangled photons at a time, each towards a filter that tested their polarization.

Alain Aspect

Allen Aspect developed a setup to close a critical loophole. He was able to switch measurement settings after an entangled pair left its source, so the setting that was present when they were emitted could not affect the result.

Anton Zeilinger

Anton Zeilinger, 2022 Nobel Prize winner in Physics, researches entangled quantum states. His research group has demonstrated a phenomenon called quantum teleportation, which makes it possible to transfer a quantum state from a particle to a distance.
