Entanglement measure for general pure multipartite quantum states

Hoshang Heydari, Gunnar Björk
2004 Journal of Physics A: Mathematical and General  
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.
