Timeline
John Francis Clauser (born December 1, 1942) is an American theoretical and experimental physicist known for contributions to the foundations of quantum mechanics, in particular the Clauser–Horne–Shimony–Holt inequality.
Clauser was awarded the 2022 Nobel Prize in Physics, jointly with Alain Aspect and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science".
Clauser was born in Pasadena, California.
His father, Francis H. Clauser, was a professor of aeronautical engineering who founded and chaired the aeronautics department at Johns Hopkins University.
He later served as the Clark Blanchard Millikan Professor of Engineering at the California Institute of Technology (Caltech).
His mother, Catharine McMillan, was the humanities librarian at Caltech and sister of 1951 Nobel Prize in Chemistry laureate Edwin McMillan.
He received a bachelor of science in physics from Caltech in 1964, where he was a member of Dabney House.
He received a master of arts in physics in 1966 and a doctor of philosophy in physics in 1969 from Columbia University under the direction of Patrick Thaddeus.
From 1969 to 1975, he worked as a postdoctoral researcher at the University of California, Berkeley and Lawrence Berkeley National Laboratory.
In 1972, working with Berkeley graduate student Stuart Freedman, he carried out the first experimental test of the CHSH-Bell's theorem predictions.
This was the first experimental observation of a violation of a Bell inequality.
In 1974, working with Michael Horne, he first showed that a generalization of Bell's Theorem provides severe constraints for all local realistic theories of nature (a.k.a. objective local theories).
That work introduced the Clauser–Horne (CH) inequality as the first fully general experimental requirement set by local realism.
It also introduced the "CH no-enhancement assumption", whereupon the CH inequality reduces to the CHSH inequality, and whereupon associated experimental tests also constrain local realism.
Also in 1974 he made the first observation of sub-Poissonian statistics for light (via a violation of the Cauchy–Schwarz inequality for classical electromagnetic fields), and thereby, for the first time, demonstrated an unambiguous particle-like character for photons.
Clauser worked as a research physicist mainly at Lawrence Livermore and Berkeley from 1975 to 1997.
In 1976 he carried out the world's second experimental test of the CHSH-Bell's Theorem predictions.
The three were also jointly awarded the 2022 Nobel Prize in Physics.
In May 2023, Clauser joined the board of the Coalition, a climate change denial organization.
In November 2023, Clauser called himself a "climate denier" at an event organized by the Deposit of Faith Coalition, a group of Catholic organizations.
He believes that Earth's temperature is primarily determined by cloud cover instead of, as stated by the scientific consensus on climate change, carbon dioxide emissions.
He has concluded that clouds have a net cooling effect on the planet, and stated "there is no climate crisis."
The consensus among meteorologists and climatologists is that low-altitude, thick clouds do have a net cooling effect, but high-altitude, thin ones have a warming effect; there is observational evidence that the overall current cloud feedback amplifies global warming, and does not have a cooling effect.
