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 ... WebMar 11, 2024 · For example, it is demonstrated, when detector efficiency is 83% the S factor of CHSH inequality will be 2, which completely agrees with famous detector efficiency …

WebSep 29, 2024 · In what follows, we show every Bell-CHSH experiment admits a local realistic theory when usual analysis says a violation of the Bell-CHSH inequality. Consider a Bell-CHSH experiment. The results of measurements are ± 1. (M + 1) is the number of measurements. N is a natural number where 1 ≤ N ≤ M. WebApr 6, 2024 · The CHSH inequality Imagine Alice and Bob are given each one part of a bipartite entangled system. Each of them then performs two measurements on their part … training ottawa

Local Reality and the CHSH Inequality - Qiskit

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 … WebMar 6, 2024 · 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), … WebMar 23, 2024 · Therefore, we have found a distribution that cannot be explained by a local model but nevertheless satisfies the CHSH inequality. We can however still get a converse statement by including relabelled versions of the CHSH inequality. these pitches be crazy
