摘要/Abstract

摘要：

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 has been investigated. The results show that three-qubit W states have unique three body entanglement and nonlocality. These results will provide theoretical foundation for the farther research of entangle feature and entangle dynamics of W states.
