论文摘要
量子非局部性是一种与量子纠缠和EPR转向更强的显着量子相关性。可以通过违反Mermin不平等的行为来检测到标准的三方非局部性。通过使用局部过滤操作，我们在Mermin运算符的最大期望值上给出了一个紧密的上限。通过详细的示例，我们表明，可以通过局部过滤来揭示隐藏的标准非局部性，从而可以增强液体纠缠状态的鲁棒性。
Quantum nonlocality is a kind of significant quantum correlation that is stronger than quantum entanglement and EPR steering. The standard tripartite nonlocality can be detected by the violation of the Mermin inequality. By using local filtering operations, we give a tight upper bound on the maximal expected value of the Mermin operators. By detailed examples we show that the hidden standard nonlocality can be revealed by local filtering which can enhance the robustness of the noised entangled states.
