We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels (MACs) with an arbitrary number of senders. As an example, we consider the bosonic thermal-loss MAC and solve the one-shot capacity region enabled by an entanglement source composed of sender-receiver pairwise two-mode squeezed vacuum states. The EA capacity region is strictly larger than the capacity region without entanglement-assistance. With two-mode squeezed vacuum states as the source and phase modulation as the encoding, we also design practical receiver protocols to realize the entanglement advantages. Four practical receiver designs, based on optical parametric amplifiers, are given and analyzed. In the parameter region of a large noise background, the receivers can enable a simultaneous rate advantage of 82.0% for each sender. Due to teleportation and superdense coding, our results for EA classical communication can be directly extended to EA quantum communication at half of the rates. Our work provides a unique and practical network communication scenario where entanglement can be beneficial.

我们用任意数量的发送者来解决量子多路访问信道（MAC）的纠缠辅助（EA）经典容量区域。例如，我们考虑了Bosonic热损耗MAC，并解决了由发送方和接收方成对的两模态压缩真空状态组成的纠缠源启用的单发容量区域。EA容量区域严格大于没有纠缠辅助的容量区域。以双模压缩真空状态为源，相位调制为编码，我们还设计了实用的接收器协议以实现纠缠优势。给出并分析了基于光参量放大器的四种实用接收机设计。在大噪声背景的参数区域中，接收器可以为每个发送器实现82.0％的同时速率优势。由于远距传输和超密编码，我们对EA经典通信的结果可以以一半的速率直接扩展到EA量子通信。我们的工作提供了一种独特而实用的网络通信方案，在这种情况下，纠缠可能会有所帮助。
