The 1969 CHSH inequality's derivation had required several minor supplementary assumptions, sometimes called "loopholes." The CH inequality's derivation eliminates those supplementary assumptions and is thus more general.

WebSep 12, 2024 · Two such inequivalent formulations of non-locality are Bell–CHSH [ 3, 7] and CGLMP [ 8, 12, 15 ]. The former involves a single inequality with two dichotomic observables at each site. The latter is a dimension-dependent inequality also with two observables per site but each having distinct eigenvalues. CGLMP reduces to … WebThe CHSH inequality is as follows: E (a,b) - E (a,b')+E (a',b)+E (a',b') \leq 2 ∣E (a,b)−E (a,b′)+E (a′,b) +E (a′,b′)∣ ≤ 2 where a a and a' a′ are two possible orientations for one Stern-Gerlach detector in a Bell experiment … crotone 88900 kr
