WebIn the past decades, many experiments have been designed to test the Bell’s inequality or Clauser-Horne-Shimony-Holt inequality [1,6{8,10]. Today, the two inequalities are of great impor-tance to quantum information and computation [3,4,11,12]. Very recently, we [5] have shown the math contradictions in Bell’s argument for his inequality. WebJul 21, 2004 · Though in their proof they employed the condition OD, this condition is unnecessary for the derivation of the inequality, as shown by Bell (1971), who provided a proof of the CHSH inequality that relies on neither the assumption of perfect anticorrelation nor an assumption of outcome determinism. easy home digital basal thermometerWebAug 26, 2002 · Bell-Clauser-Horne-Shimony-Holt inequality (in terms of correlation functions) of two qutrits is studied in detail by employing tritter measurements.

"WebNov 10, 2024 · 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 it is not required.
