    "abstract": "Cirel\u0027son inequality states that the absolute value of the combination of\nquantum correlations appearing in the Clauser-Horne-Shimony-Holt (CHSH)\ninequality is bound by $2 \\sqrt 2$. It is shown that the correlations of two\nqubits belonging to a three-qubit system can violate the CHSH inequality beyond\n$2 \\sqrt 2$. Such a violation is not in conflict with Cirel\u0027son\u0027s inequality\nbecause it is based on postselected systems. The maximum allowed violation of\nthe CHSH inequality, 4, can be achieved using a Greenberger-Horne-Zeilinger\nstate.",
