英文摘要	We revisit the criterion of multiparticle entanglement based on the overlaps of a given quantum state p with maximally entangled states. For a system of in particles, each with N distinct states, we prove that p is m-particle negative partial transpose entangled, if there exists a maximally entangled state \MES), such that (MES\rho\MES) > 1/N. While this sufficiency condition is weaker than the Peres-Horodecki criterion in all cases, it applies to multi-particle systems, and becomes especially useful when the number of particles (m) is large. We also consider the converse of this criterion and illustrate its invalidity with counter examples.
