Seminar 7. Non-local games

At the seminar we started the talk about the phenomenon of Bell nonlocality. It is convenient to study this phenomenon using the formalism of nonlocal games. We introduced the notions of nonlocal game, non-signalling correlations, local strategies . We considered the Clauser-Horn-Shimoni-Holt functional and showed that for local correlations it takes $\leq 2$ and $\geq -2$.
