The CHSH game is a thought experiment involving two parties separated at a great distance (far enough to preclude classical communication at the speed of light), each of whom has access to one half of an entangled two-qubit pair. Analysis of this game shows that no classical local hidden-variable … See more In physics, the CHSH inequality can be used in the proof of Bell's theorem, which states that certain consequences of entanglement in quantum mechanics cannot be reproduced by local hidden-variable theories. … See more The usual form of the CHSH inequality is where a and a′ are detector settings on side A, b and b′ on side B, … See more The original 1969 derivation will not be given here since it is not easy to follow and involves the assumption that the outcomes are all +1 or −1, never zero. Bell's 1971 derivation is more general. He effectively assumes the "Objective Local Theory" later used … See more • Correlation does not imply causation • Leggett–Garg inequality • Quantum game theory See more Many Bell tests conducted subsequent to Alain Aspect's second experiment in 1982 have used the CHSH inequality, estimating the terms using (3) and assuming fair sampling. Some dramatic violations of the inequality have been reported. See more In experimental practice, the two particles are not an ideal EPR pair. There is a necessary and sufficient condition for a two-qubit density matrix $${\displaystyle \rho }$$ to violate the CHSH inequality, expressed by the maximum attainable polynomial Smax … See more WebOct 16, 2024 · β ≈ 2.4547 (dashed line) is the optimal CHSH value found by using an analytical expression.

Alain Aspect (and others) ran the experiment, and the results were fully consistent with quantum mechanics, and extremely problematic for local hidden variable theories.
WebA CHSH experiment Recall the CHSH inequality discussed in the lecture, where Alice has the option to measure two observables A1, A2, and Bob has the option to measure two observables B1, B2. A simple experimental test of this inequality can be found by taking the EPR state, sending one particle to Alice and the other to Bob, and having them ...
