    "abstract": "Based on a geometrical argument introduced by Zukowski, a new multisetting\nBell inequality is derived, for the scenario in which many parties make\nmeasurements on two-level systems. This generalizes and unifies some previous\nresults. Moreover, a necessary and sufficient condition for the violation of\nthis inequality is presented. It turns out that the class of non-separable\nstates which do not admit local realistic description is extended when compared\nto the two-setting inequalities. However, supporting the conjecture of Peres,\nquantum states with positive partial transposes with respect to all subsystems\ndo not violate the inequality. Additionally, we follow a general link between\nBell inequalities and communication complexity problems, and present a quantum\nprotocol linked with the inequality, which outperforms the best classical\nprotocol.",
