    "abstract": "In this paper, we discuss the partial separability and its criteria problems\nof multipartite qubit mixed-states. First we strictly define what is the\npartial separability of a multipartite qubit system. Next we give a reduction\nway from N-partite qubit density matrixes to bipartite qubit density matrixes,\nand prove a necessary condition that a N-partite qubit mixed-state to be\npartially separable is its reduction to satisfy the PPT condition.\n  PACC numbers: 03.67.Mn; 03.65.Ud; 03.67.Hk",
