Abstract
In this paper, we study the multipartite entanglement properties of graph states up to seven qubits. Our analysis shows that the generalized concurrence measure (GCM) is more efficient than geometric entanglement measure (GEM) for measuring entanglement quantity in the multi-qubit graph states.
