对GHZ态与W态叠加的三粒子广义GHZ态,用Svetlichny不等式,给出了其非定域性的解析表达式.用数值计算方法讨论了纠缠与非定域性之间的关系.
With the help of Svetlichnys 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.
