我们提出了一种方法来获得不同类别的多粒子纠缠，特别是真正的多粒子纠缠的可分性准则。由此产生的标准是必要的和充分的某些家庭的国家。例如，这完全解决了根据其可分性和纠缠特性对混合有白色噪声的N量子比特Greenberger-Horne-Zeilinger态进行分类的问题。此外，该标准是上级的所有已知的纠缠标准，许多其他家庭，也允许检测绑定纠缠。接下来，我们证明了它们在实验中是容易实现的，并讨论了多粒子纠缠态退相干的应用。
We present a method to derive separability criteria for different classes of multiparticle entanglement, especially genuine multiparticle entanglement. The resulting criteria are necessary and sufficient for certain families of states. This, for example, completely solves the problem of classifying N-qubit Greenberger-Horne-Zeilinger states mixed with white noise according to their separability and entanglement properties. Further, the criteria are superior to all known entanglement criteria for many other families; also they allow the detection of bound entanglement. We next demonstrate that they are easily implementable in experiments and discuss applications to the decoherence of multiparticle entangled states.
