WebFeb 16, 2016 · 2. Your derivation is pretty standard, but, under influence of computer science, there has been a tendency over the last decade to present the CHSH inequality as a game with binary output being 0 or 1 instead of ±1, hence a shift in presentation towards conditional probalilities instead of expectation values. As you have guessed, the equality. WebBound for the CHSH inequality. The first Tsirelson bound was derived as an upper bound on the correlations measured in the CHSH inequality.It states that if we have four dichotomic observables , , , (i.e., two observables for Alice and two for Bob) with outcomes +, such that [,] = for all ,, then + + . For comparison, in the classical case (or local realistic …

WebNov 10, 2024 · 5. The difference is as follows: the original Bell inequality requires that outcomes from the same setting are always perfectly anti-correlated. It says nothing about the case where they are even marginally different. by contrast, in CHSH, the ideal (giving maximum violation) is that outcomes from the same setting would be anti-correlated, but ...
