Using this, we must choose angles for which it is possible to violate Bell’s inequality. The CHSH inequality uses a correlation of the probabilities defined as follows:

Webthe 1980s, technology had advanced to the point where playing the CHSH game was actually a feasible physics experiment! Alain Aspect (and others) ran the experiment, and the results were fully consistent with quantum mechanics, and extremely problematic for local hidden variable theories.
