John Clauser
John Clauser is an American physicist who helped turn a philosophical dispute about quantum mechanics into an experimental test. He shared the 2022 Nobel Prize in Physics with Alain Aspect and Anton Zeilinger.
Early life
Scientific family
His father was an aeronautical engineer and his mother a humanities librarian at Caltech.
Physics training
Studied at Caltech before completing his doctorate at Columbia University in 1969.
Career
- 1969
Berkeley research
Began postdoctoral work at Berkeley and Lawrence Berkeley Laboratory.
- 1975–1997
Laboratory physicist
Worked principally at the Berkeley and Livermore laboratories.
- 2022
Nobel recognition
Shared the physics prize for experiments with entangled photons.
Contributions
CHSH inequality
Co-developed a practical mathematical test of local explanations for quantum correlations.
Freedman–Clauser experiment
With Stuart Freedman, measured photon correlations that violated a Bell inequality.
Clauser–Horne inequality
With Michael Horne, developed a more general experimental test.
Beyond the lab
Independent research
Continued experimental work outside a conventional university professorship.
Scientific discussion
Helped circulate Epistemological Letters, a newsletter debating quantum foundations.
