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 ... 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 …
WebDec 6, 2024 · In this work, we perform an experimental violation of the CHSH inequality under a scenario when one party performs noisy measurements, which is known as an asymmetric Bell experiment. WebOct 1, 2014 · 2. The CHSH inequality is a statement about a linear combination of expectation values of different products of observables. It is not a statement about the outcome of a single measurement. Thus, violation of the CHSH inequality can only be inferred in a statistical sense after performing many repetitions of the experiment.
Webthe CHSH inequality in the classical probabilistic frame, is usually linked with the physical concept of ”local realism”. The latter refers (see, for example, [5], page 160) to those situations where, under a joint experiment, set-ups … Webin our experiment by recording the number of coincident signal/idler photon pairs detected at the APDs when the polarizers are aligned to the different combinations of angles. Using this, we must choose angles for which it is possible to violate Bell’s inequality. The CHSH inequality uses a correlation of the probabilities defined as follows:

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.
