A simple entanglement measure for multipartite pure states
Feng Pan, Dan Liu, Guoying Lu, Jerry Paul Draayer · 2004
A simple entanglement measure for multipartite pure states is formulated based on the partial entropy of a series of reduced density matrices. Use of the proposed new measure to distinguish disentangled, partially entangled, and maximally entangled multipartite pure states is illustrated. © 2004 Springer Science+Business Media, Inc.
