论文摘要
线性n位本地网络与基于量子的中继器纠缠分布协议兼容。不完美的不同来源，例如纠缠产生中的错误，噪声量子通道的通信以及测量中的瑕疵导致此类网络之间的量子性衰减。从实际的角度来看，必须在存在不同类型的噪声的情况下分析量子网络相关性的非经典性。当前的讨论提供了噪声网络方案中量子相关性非N-Local特征的形式表征。在这种情况下，已经引入了非N-局部性的持久性。这样的概念有助于分析网络相关的非N-Local特征的衰减，而在存在一个或多个缺陷原因的情况下，线性网络长度的增加。
Linear n-local networks are compatible with quantum repeaters based entanglement distribution protocols. Different sources of imperfections such as error in entanglement generation, communication over noisy quantum channels and imperfections in measurements result in decay of quantumness across such networks. From practical perspectives it becomes imperative to analyze non classicality of quantum network correlations in presence of different types of noise. Present discussion provides a formal characterization of non n-local feature of quantum correlations in noisy network scenario. In this context, persistency of non n-locality has been introduced. Such a notion helps in analyzing decay of non n-local feature of network correlations with increasing length of the linear network in presence of one or more causes of imperfections.
