论文摘要
在网络中，渠道将旨在建立通信协议的各方引入相关性。在这项工作中，我们通过利用铃铛方案来展示非本地网络编码的框架，并显示非本地和量子资源在网络编码中的有用性。考虑了两者和两局托管干扰通道，其网络编码的特征是两输入和四个结果铃声。结果表明，与量子（局部）相关性相比，非信号（量子）相关性通常导致严格更高的通道能力。但是，还表明，更多的非局部性并不一定意味着更高的通道容量。该框架通常可以应用于网络通信协议。
In a network, a channel introduces correlations to the parties that aim to establish a communication protocol. In this work, we present a framework of non-local network coding by exploiting a Bell scenario and show the usefulness of non-local and quantum resources in network coding. Two-sender and two-receiver interference channels are considered, for which network coding is characterized by two-input and four-outcome Bell scenarios. It is shown that non-signaling (quantum) correlations lead to strictly higher channel capacities in general than quantum (local) correlations. It is also shown that, however, more non-locality does not necessarily imply a higher channel capacity. The framework can be generally applied to network communication protocols.
