Abstract

We obtain a single general Bell inequality that summarizes all possible Bell type constrains on the correlation function for the N-particle system. This is for the case where measurements on each particle can be chosen between two arbitrary dichotomic observables. We also obtain a simple condition for an arbitrary N-qubit mixed state to violate that general Bell inequality.
