What exactly does $S$ represent in the CHSH inequality

WebMar 17, 2024 · One of the most important Bell inequalities is the Clauser–Horne–Shimony–Holt (CHSH) inequality [ 10] for two-qubit systems. In [ 11] Horodeckis have presented the necessary and sufficient condition of violating the CHSH inequality by an arbitrary mixed two-qubit state. 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. WebCHSH inequality 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.

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.

WebMar 6, 2024 · Tsirelson's inequality, discovered by Boris Tsirelson in 1980, [16] states that for any quantum strategy S for the CHSH game, the bias β CHSH ∗ ( S) ≤ 1 2. Equivalently, it states that success probability ω CHSH ∗ ( S) ≤ cos 2 ( π 8) = 1 2 + 1 2 2 for any quantum strategy S for the CHSH game.
