This talk presents quantum mechanical inequalities which distinguish, for systems of N spin-1/2 particles (N>2), between fully entangled states and states in which at most N-1 particles are entangled.
These inequalities are stronger than those obtained by Gisin and Bechmann-Pasquinucci [Phys. Lett. A 246, 1 (1998)] and by Seevinck and Svetlichny [quant-ph/0201046].
