Violating bell's inequality beyond Cirel'son's bound
(American Physical Society, 2002-02-11)
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 ...

Two qubits of a W state violate Bell's inequality beyond Cirel'son's bound
(American Physical Society, 2002-10)
It is shown that the correlations between two qubits selected from a trio prepared in a W state violate the Clauser-Horne-Shimony-Holt inequality more than the correlations between two qubits in any quantum state. Such a ...
