Under the dual assumptions of localization and reality, this theorem establishes strict restrictions on the possible correlation degree of the results when two separated particles are measured at the same time. In classical physics, this inequality holds; In quantum physics, this inequality does not hold, that is, there is no such theory, and its mathematical form is ∣Pxz-Pzy∣≤ 1+Pxy.
The current experiments show that quantum mechanics is correct, and the theory of localized hidden variables of determinism is not valid. The failure of Bell inequality means that the prediction of local realism advocated by Albert Einstein does not conform to the theory of quantum mechanics. Because the results of many experiments are consistent with the predictions of quantum mechanics theory.
The quantum correlation shown is far stronger than that explained by the local hidden variable theory, so physicists refuse to accept the explanation of these experimental results by the local entity theory.
Belzi people
1928 On July 28th, John Stewart Bell was born in Belfast, the capital of Northern Ireland. /kloc-entered Queen's University of Belfast at the age of 0/7 to study physics. Although his major is experimental physics, he also showed extraordinary interest in theoretical physics.
Especially the quantum theory, which is in the ascendant, shows profound philosophical connotation, and Jambers is quite addicted to it. But Bell was noncommittal about the Copenhagen explanation of probability theory. What Bell wants is a clear and objective physical theory. He claimed to be a loyal follower of Einstein.
