Violating bell's inequality beyond Cirel'son's bound

Cirel’son inequality states that the absolute value of the combination of quantum correlations appearing in the Clauser-Horne-Shimony-Holt (CHSH) inequality is bound by 2 √ 2. It is shown that the correlations of two qubits belonging to a three-qubit system can violate the CHSH inequality beyond 2 √...
