| Abstract: | With the help of Svetlichny's inequality, we obtain an analytical expression of the quantum nonlocality for generalized Greenberger-Horne-Zeilinger(GHZ) state composed of a (GHZ) state and a W state. The numerical results between tripartite entanglement and nonlocality for generalized GHZ state are discussed. |
