Next, we focus … In the CHSH game, there are two cooperating players, Alice and Bob, and a referee, Charlie. These agents will be abbreviated respectively. At the start of the game, Charlie chooses bits uniformly at random, and then sends to Alice and to Bob. Alice and Bob must then each respond to Charlie with bits … See more 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. … 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.

WebA quantum strategy for the CHSH game¶. What is very intriguing about the CHSH game is that it is an example of a nonlocal game where the players can do strictly better if they make use of a quantum strategy instead of a classical one.
