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 … WebSep 20, 2024 · That prediction is the 1974 Clauser–Horne (CH) inequality. 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.
