In physics, the CHSH inequality can be used in the proof of Bell's theorem, which states that certain consequences of entanglement in quantum mechanics cannot be reproduced by local hidden-variable theories. Experimental verification of the inequality being violated is seen as confirmation that nature … See more The usual form of the CHSH inequality is where a and a′ are detector settings on side A, b and b′ on side B, the four combinations being tested in separate subexperiments. The terms E(a, b) … See more Many Bell tests conducted subsequent to Alain Aspect's second experiment in 1982 have used the CHSH inequality, estimating the terms using (3) and assuming fair … See more In experimental practice, the two particles are not an ideal EPR pair.

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. Web9. I'm aware that the optimality of the quantum strategy for the CHSH game is given by Tsirelson's bound, but presentations all skip over the (admittedly much less interesting) proof of the classical strategy's optimality. In the CHSH game, we have two players: Alice and Bob. They are separately given independent random bits X and Y as input ...

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.
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. shared roadsWebSep 9, 2014 · The purpose of the inequality is to make it easy to conduct Bell tests.
