In addition to Bell's original inequality, [3] the form given by John Clauser, Michael Horne, Abner Shimony and R. A. Holt, [8] (the CHSH form) is especially important [8], as it gives classical limits to the expected correlation for the above experiment conducted by Alice and Bob:

Webinequality is derived under the assumption that there exist hidden local vari-ables and prescribes a constrain on the expected values of a Bell test experiment. Experimental … 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.
