(Published: 2022.12.13.)

The Clauser-Horne-Shimony-Holt game is the simplest scenario in which the use of nonlocal no-signaling resources can be understood. In fact it is a game that is behind the classic Clauser-Horne-Shimony-Holt (CHSH) inequality that is famous for having a quantum violation. The game is also mentioned on the Wikipedia page of the celebrated inequality, and in many other works.
