论文摘要
网络场景为量子非局部性现象提供了有趣的新观点。值得注意的是，当考虑具有独立源的网络时，可以在不需要测量输入的情况下证明量子非局部性，即各方进行固定的量子测量。在这里，我们的目标是找到这种效果的最小例子。为了关注三角网络的最小情况，我们介绍了涉及$ 3-3-3 $和$ 3-3-2 $的输出红衣的示例。最后，我们讨论了在具有二进制输出的三角网络中找到量子非局部性的示例的前景，并指出与lovasz局部引理的连接。
The network scenario offers interesting new perspectives on the phenomenon of quantum nonlocality. Notably, when considering networks with independent sources, it is possible to demonstrate quantum nonlocality without the need for measurements inputs, i.e. with all parties performing a fixed quantum measurement. Here we aim to find minimal examples of this effect. Focusing on the minimal case of the triangle network, we present examples involving output cardinalities of $3-3-3$ and $3-3-2$. Finally, we discuss the prospects of finding an example of quantum nonlocality in the triangle network with binary outputs, and point out a connection to the Lovasz local lemma.
