We present a set of Bell inequalities for multiqubit quantum systems. These Bell inequalities are shown to be able to detect multiqubit entanglement better than previous Bell inequalities such as Werner-Wolf-Zukowski-Brukner ones. Computable formulas are presented for calculating the maximal violations of these Bell inequalities for any multiqubit states.

Abstract We present a set of Bell inequalities for multi-qubit quantum systems. These Bell inequalities are shown to be able to detect multi-qubit entanglement better than previous Bell inequalities such as WWZB ones. Computable formulas are presented for calculating the maximal violations of these Bell inequalities for any multi-qubit states.
