摘要:

研究了CHSH不等式和V $\grave{e}$ rtesi不等式在局部滤波操作下的最大违反行为.给出了一般两量子比特系统在局部滤波操作下计算CHSH不等式最大破坏和V $\acute{e}$ rtesi不等式最大破坏下界的解析方法.通过实例证明了存在量子态,其非定域性可以用V $\acute{e}$ rtesi不等式代替CHSH不等式进行局域滤波运算后得到.

英文摘要:

We investigate the behavior of the maximal violations of the CHSH inequality and V$\grave{e}$rtesi's inequality under the local filtering operations. An analytical method has been presented for general two-qubit systems to compute the maximal violation of the CHSH inequality and the lower bound of the maximal violation of V$\acute{e}$rtesi's inequality over the local filtering operations. We show by examples that there exist quantum states whose non-locality can be revealed after local filtering operation by the V$\acute{e}$rtesi's inequality instead of the CHSH inequality.
