John Francis Clauser (born December 1, 1942 in Pasadena , California ) is an American experimental physicist who deals with the fundamentals of quantum mechanics .

Clauser is the son of a professor for aircraft construction ( Francis Hettinger Clauser , * 1913) at Caltech and studied at Caltech ( Bachelor 1964) and at Columbia University , where he obtained his master’s degree in 1966 and in 1969 with Patrick Thaddeus on the measurement of the cosmic Doctorate in microwave background . He then worked at the Lawrence Berkeley National Laboratory until 1975 and at the Lawrence Livermore National Laboratory from 1975 to 1986 . He then worked as a research physicist at the University of California, Berkeley . In a basic experiment, he tested with Stuart Freedman , the Bell's Theorem , which they previously to inequality CHSH (Clauser, Michael Horne , Abner Shimony and Richard Holt 1969) generalized. That was the first observation of quantum entanglement and the first experiment that showed the violation of Bell's inequality (and thus confirmed quantum mechanics). Then he dealt with atomic interferometers .

He also dealt with the confinement of plasmas with magnetic mirrors ( magnetic flask ).

In 2010 he received the Wolf Prize in Physics with Alain Aspect and Anton Zeilinger .

According to the recollections of Clauser, this type of experiment was received very critically at the time and only the support of Charles H. Townes made it possible to carry out in Berkeley.
