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 ... WebThis answer to a related question provides a discussion of how these interpretations tie into the results from Bell's inequality. (1) Quantum mechanics predicts 25% or more will correlate. (2) Bell says hidden variables should correlate 33% or more of the time. (3) The difference between the two is Bell's inequality.
