dc.description.abstract	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 √ 2. Such a violation is not in conflict with Cirel’son’s inequality because it is based on postselected systems. The maximum allowed violation of the CHSH inequality, 4, can be achieved using a Greenberger-Horne-Zeilinger state.	es
