Chsh bell inequality
WebThe Bell inequality [1-3] and the CHSH inequality [4] describe the relation between the statistical data observed underjoint experiments. Theoriginal derivations of these inequalities (and their further numerous generalizations and strengthenings) are based on the structure of probability theory, associated with the formalism of random variables. Webmatrix representations. Although the Bell-CHSH inequality turns out to be violated, the size of the violation is different for different representations, the maximum vio-lation being given by Tsirelson’s bound. The feature relies on a pairing mechanism between the modes of the entangled state employed to test the Bell-CHSH inequality. 1 ...
