John Francis Clauser (/ ˈklaʊzər /; 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. [1] Clauser was awarded the 2022 Nobel Prize in Physics, jointly with Alain Aspect and Anton Zeilinger ...
Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement. "Local" here refers to the principle of locality, the idea that a particle can only be influenced ...
t. e. A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein 's concept of local realism. Named for John Stewart Bell, the experiments test whether or not the real world satisfies local realism, which requires the ...
Edward S. Fry and Randall C. Thompson Texas A&M University, reattempted the experiment in 1973 and agreed with Clauser. [8] These experiments were only a limited test, because the choice of detector settings was made before the photons had left the source. [8] Advised by John Bell, Alain Aspect worked to develop an experiment to remove this ...
Quantum mechanics. Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
Alain Aspect (French: ⓘ; born 15 June 1947 [3]) is a French physicist noted for his experimental work on quantum entanglement. [4] [5] [6] [7]Aspect was awarded the 2022 Nobel Prize in Physics, jointly with John Clauser and Anton Zeilinger, "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science".
CHSH stands for John Clauser, Michael Horne, Abner Shimony, and Richard Holt, who described it in a much-cited paper published in 1969. [1] They derived the CHSH inequality, which, as with John Stewart Bell 's original inequality, [ 2 ] is a constraint—on the statistical occurrence of "coincidences" in a Bell test —which is necessarily true ...
In a review of Kaiser's book in Physics Today, Silvan Schweber challenges Kaiser's views of the importance of the Fundamental Fysiks Group. He writes that Bell's Theorem was not obscure during the preceding decade, but was worked on by authors such as John Clauser (who was a member of the group) and Eugene Wigner.
