Explain the concept of Bell's inequality and its role in testing local realism.
Bell's inequality is a fundamental concept in the field of quantum information that plays a important role in testing the validity of local realism. Local realism is a philosophical concept that suggests that physical systems have predetermined properties and that these properties are independent of any measurement or observation. Bell's inequality provides a means to

How do Alice and Bob use their shared entangled state to generate non-local correlations in the CHSH game?
In the field of Quantum Information, the concept of entanglement plays a important role in understanding the phenomenon of non-local correlations. Alice and Bob, two distant parties, can utilize their shared entangled state to generate these correlations in a game known as the CHSH game, which stands for Clauser-Horne-Shimony-Holt inequality. This game serves as a
