论文摘要
与贝尔场景相反，即使所有各方都没有随机选择输入的自由，也可以利用量子非局部性。在涉及独立来源的网络中，非局部性的这种表现是可能的。人们可以利用量子网络的这种特征来纠缠两分量子状态。在这种情况下，我们表征了在某些当事方执行固定测量时，在涉及有限数量来源的网络中模拟的相关性。除了双方纠缠之外，我们对涉及现在产生纯三方量子状态的来源的网络进行了询问。有趣的是，在这里，在这里选择的随机性也不是每个方生成非局部相关性的必要条件。
Contrary to Bell scenario, quantum nonlocality can be exploited even when all the parties do not have freedom to select inputs randomly. Such manifestation of nonlocality is possible in networks involving independent sources. One can utilize such a feature of quantum networks for purpose of entanglement detection of bipartite quantum states. In this context, we characterize correlations simulated in networks involving finite number of sources generating quantum states when some parties perform fixed measurement. Beyond bipartite entanglement, we enquire the same for networks involving sources now generating pure tripartite quantum states. Interestingly, here also randomness in input selection is not necessary for every party to generate nonlocal correlation.
