摘要：
We investigate the hierarchical structure of the n-partite quantum states. We present several types of parameterized multipartite entanglement measures. Rigorous proofs show that the proposed k-nonseparable measures satisfy all the requirements for being an entanglement measure including the entanglement monotone, strong monotone, convexity, vanishing on all k-separable states, and being strictly greater than zero for all k-nonseparable states. The hierarchical measures proposed by us embody advantages in distinguishing same class entangled states and measuring continuity.
