Seminar 8. Bell inequalities and Tsirelson bound. Yu. P. Anosov
https://youtu.be/4k29Q6C8G0M Abstract: On this seminar we continued our talk on Bell's non-locality. We repeated what non-local games are and considered the case where players have the resource of quantum entanglement. Non-local correlations allow us to improve the estimate in the CHSH inequality to a value $\leq 2\sqrt{2}$ (Tsirelson's bound). We discussed the strategies under which this bound is reached. In addition, in general, there are behaviours not allowed by quantum mechanics under which the $4$ estimate is reached.
