Query: Efficient Entanglement Measure for Graph States   In this paper, we study the multipartite entanglement properties of graph
states up to seven qubits. Our analysis shows that the generalized concurrence
measure is more efficient than geometric entanglement measure for measuring
entanglement quantity in the multi-qubit graph states.
