    "abstract": "We give a complete, hierarchic classification for arbitrary multi-qubit mixed\nstates based on the separability properties of certain partitions. We introduce\na family of N-qubit states to which any arbitrary state can be depolarized.\nThis family can be viewed as the generalization of Werner states to multi-qubit\nsystems. We fully classify those states with respect to their separability and\ndistillability properties. This provides sufficient conditions for\nnonseparability and distillability for arbitrary states.",
