The Mermin inequality provides a criterion for experimentally ruling out local-realistic descriptions of multiparticle systems. A violation of this inequality means that the particles must be entangled, but does not, in general, indicate whether N -partite entanglement is present. For this, a stricter bound is required. Here we discuss this bound and use it to propose two different schemes for demonstrating N -partite entanglement with atoms. The first scheme involves Bose–Einstein condensates trapped in an optical lattice and the second uses Rydberg atoms in microwave cavities.
