论文摘要
未来的量子互联网依赖于大规模的纠缠分布。量子分解是大规模网络中的重要障碍，否则在源和目的地之间的多个路径方面表现更好。我们提出了一个新的拓扑，连接的树，并具有大量冗余边缘，以支持纠缠对的多路路线路由。我们定性地分析了量子网络的可扩展性，以使不同拓扑的最大用户容量的最大用户能力分析。我们的分析表明，与分布更均匀分布的晶格拓扑相比，薄连接的树网络可以容纳更多的用户对。我们将分析扩展到量子密钥分布，并表明薄树拓扑的量子网络对腐蚀性更强大，并且可以在多个交流方之间获得更好的钥匙分布。
Future quantum internet relies on large-scale entanglement distribution. Quantum decoherence is a significant obstacle in large-scale networks, which otherwise perform better with multiple paths between the source and destination. We propose a new topology, connected tree, with a significant amount of redundant edges to support multi-path routing of entangled pairs. We qualitatively analyse the scalability of quantum networks to maximum user capacity in decoherence for different topologies. Our analysis shows that thin-connected tree networks can accommodate a larger number of user pairs than more evenly distributed lattice topology. We extend our analysis to quantum key distribution and show that the quantum network of a thin tree topology is more robust against decoherence and leads to better key distribution among multiple communicating parties.
