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. There is a necessary and sufficient condition for a two-qubit density matrix $${\displaystyle \rho }$$ to violate the CHSH inequality, expressed by the maximum attainable polynomial Smax … See more • Correlation does not imply causation • Leggett–Garg inequality • Quantum game theory See more The original 1969 derivation will not be given here since it is not easy to follow and involves the assumption that the outcomes are all +1 or −1, never zero. Bell's 1971 derivation is more general. He effectively assumes the "Objective Local Theory" later used … See more The CHSH game is a thought experiment involving two parties separated at a great distance (far enough to preclude classical communication at the speed of light), each of whom has access to one half of an entangled two-qubit pair. Analysis of this game shows that … See more 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 + + .

Web著名的贝尔不等式和 chsh 不等式都是在局域隐变量理论的框架下推导得到的,因此它们可以用以检验局域隐变量理论。近代的多次实验都否定了局域隐变量理论。下文给出详细推导贝尔不等式和 chsh 不等式的方法。 背景 … Webどちらの試験も、Clauser-Horne-Shimony-Holt版のベル不等式(CHSH不等式)を著しく違反している。 観測されたCHSH不等式の不等式違反は、成分概念的実体間の強い量子絡み合いの結果として説明できることを示す。 参考スコア(独自算出の注目度): 0.0 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 ... flower child store columbus ohio
