QUANTUM INFORMATION THEORY The CHSH Inequality

WebThe strength of such a nonlocal coordination between two systems is captured by a parameter c ∈ [− 1, 1] called the Bell–CHSH correlator. Bob’s probability of guessing the value of Alice’s bit correctly is (1 + c) / 2. The Bell–CHSH inequality states that c ≤ 1 / 2 in a world governed by classical (non-quantum) mechanics [1,4]. 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 ...
