John F. Clauser, Alain Aspect and Anton Zeilinger won the 2022 Nobel Prize in Physics. The award recipients were announced Tuesday at the Royal Swedish Academy of Sciences in Stockholm.

They won the prize for “experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”, the Nobel Committee said.

Eva Olsson, a member of the Nobel committee said: “Quantum information science is a vibrant and rapidly developing field. It has broad and potential implications in areas such as secure information transfer, quantum computing and sensing technology.”

Last year, the prize was awarded to three scientists – Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi.

Who is John F. Clauser ?

Clauser is an American theoretical and experimental physicist known for contributions to quantum mechanics, especially the Clauser–Horne–Shimony–Holt inequality.

The 79-year-old was born in Pasadena, California. He received his B.S. in physics from the California Institute of Technology in 1964. He then did his M.A. in physics in 1966 and his Ph.D. in physics in 1969 from Columbia University.

From 1969 to 1996, he worked mainly at Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, and the University of California, Berkeley.

In 1972, he was associated with Stuart Freedman, where he carried out the first experimental test of the CHSH-Bell’s theorem predictions.

In 1974 while he was with Michael Horne, he first showed that a generalization of Bell’s Theorem. This introduced the Clauser–Horne (CH) inequality as the first fully general experimental requirement set by local realism.

The same year, he made the first observation of sub-Poissonian statistics for light.

He was awarded the Wolf Prize in Physics in 2010 together with Alain Aspect and Anton Zeilinger.
