A simple entanglement measure for multipartite pure states

Quantum Physics 2009-11-10 v2

Abstract

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.
