Entanglement Property and Monogamy Relation of Gerneralized Mixed W
We introduce a new class of multipartite entangled mixed states with pure
state decompositions of generalized W states, similar to Schmidt-correlated
states having generalized GHZ states in the pure state decomposition. The
entanglement and separability properties are studied according to PPT
operations. Monogamy relations linked to these states are also investigated.Comment: 8 page
Entanglement measure for general pure multipartite quantum states
We propose an explicit formula for an entanglement measure of pure
multipartite quantum states, then study a general pure tripartite state in
detail, and at end we give some simple but illustrative examples on four-qubits
and m-qubits states.Comment: 5 page
