On General Measure of Entanglement Hi, sirs My major is computer science. While I currently need to deal with some physical problems. Thank you very much for your help. It is well-known that Von Neumann entropy is a measure of entanglement for bipartite pure states. However, I think that the effectiveness of this measure depends on the existence of the Schmidt decomposition for bipartite pure states. If we want to measure multipartite entanglement, it seems that the interpretation of Schmidt decomposition can not be expanded directly. Might you kindly tell me some messures on multipartite entanglement? Thanks a lot!
