三体W态的纠缠与非定域性OA北大核心CSCDCSTPCD
Entanglement and non-locality of three-qubit W states
计算了三体W态的Svetlichny不等式,给出了W态非定域性的解析表达式,讨论了W态的剩余纠缠.结果表明三体W态有着独特的共生纠缠和非定域特性,为进一步研究W态各量子比特之间的纠缠特性以及纠缠动力学提供了理论依据.
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.
