Chsh experiment

WebThe CHSH experiments slow the generation of photon pairs from one BBO so that at least 25ns separates the pairs in time. That seems to make the state of the polarization known, not indeterminate. When one of the detectors is set to match vertical polarization, one of its counters registers vertical polarization and the other registers ... WebExperiments Using The CHSH Test. Many Bell test experiments conducted subsequent to Aspect's second experiment in 1982 have used the CHSH inequality, estimating the …

Should S always be more than 2 to violate CHSH inequality?

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.

In practice most actual experiments have used light, assumed to be emitted in the form of particle-like photons (produced by atomic cascade or spontaneous parametric down conversion), rather than the atoms that Bell originally had in mind. The property of interest is, in the best known experiments, the polarisation direction, though other properties can be used. Such experiments fall into two …
