| Abstract: | The threshold value of Svetlichny inequality of three-qubit W states was calculated.The analytic expression of nonlocality for W states was introduced.And the relation between three body entanglement and nonlocality was investigated.The results show that three-qubit W states have unique three body entanglement and nonlocality.These results will provide theoretical foundation for the further research of entanglement feature and entanglement dynamics of W states. |

| Keywords: | quantum optics W states three body entanglement Svetlichny inequality nonlocality |
