Abstract
We consider quantum systems composed of $N$ qubits, and the family of all\nBell's correlation inequalities for two two-valued measurements per site. We\nshow that if a $N$-qubit state $\\rho$ violates any of these inequalities, then\nit is at least bipartite distillable. Indeed there exists a link between the\namount of Bell's inequality violation and the degree of distillability. Thus,\nwe strengthen the interpretation of Bell's inequalities as detectors of useful\nentanglement.\n
