    "abstract": "In this Letter we find the new criteria of separability of multipartite qubit\ndensity matrixes. Especially, we discuss in detail the criteria of separability\nfor tripartite qubit density matrixes. We find the sufficient and necessary\nconditions of separability for tripartite qubit density matrixes, and give two\ncorollaries. The second corollary can be taken as the criterion of existence of\nentanglement for tripartite qubit density matrixes. In concrete application,\nits steps are quite simple and easy to operate. Some examples, discussions and\nthe generalization to more high dimensional multipartite qubit density matrixes\nare given.",
