The Nobel Prize in Physics 2022

The Nobel Prize in Physics 2022 was awarded jointly to Alain Aspect, John F. Clauser and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science"

Alain Aspect
The Nobel Prize in Physics 2022

Born: 15 June 1947, Agen, France

Affiliation at the time of the award: Institut d’Optique Graduate School – Université Paris-Saclay, Paris, France; École Polytechnique, Palaiseau, France

Prize motivation: “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”

Work

One of the most remarkable traits of quantum mechanics is that it allows two or more particles to exist in what is called an entangled state. What happens to one of the particles in an entangled pair determines what happens to the other particle, even if they are far apart. In 1981–1982, Alain Aspect conducted groundbreaking experiments using entangled light particles, photons. These and other experiments confirm that quantum mechanics is correct and pave the way for quantum computers, quantum networks and quantum encrypted communication.

John F. Clauser
The Nobel Prize in Physics 2022

Born: 1 December 1942, Pasadena, CA, USA

Affiliation at the time of the award: J.F. Clauser & Assoc., Walnut Creek, CA, USA

Prize motivation: “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”

In 1972, John Clauser conducted groundbreaking experiments using entangled light particles, photons. This and other experiments confirm that quantum mechanics is correct and pave the way for quantum computers, quantum networks and quantum encrypted communication.

Anton Zeilinger
The Nobel Prize in Physics 2022

Born: 20 May 1945, Ried im Innkreis, Austria

Affiliation at the time of the award: University of Vienna, Vienna, Austria; Institute for Quantum Optics and Quantum Information, Austrian Academy of Sciences, Vienna, Austria

Prize motivation: “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”

One of the most remarkable traits of quantum mechanics is that it allows two or more particles to exist in what is called an entangled state. What happens to one of the particles in an entangled pair determines what happens to the other particle, even if they are far apart. In 1997–1998, Anton Zeilinger conducted groundbreaking experiments using entangled light particles, photons. These and other experiments confirm that quantum mechanics is correct and pave the way for quantum computers, quantum networks and quantum encrypted communication.
