论文摘要
我们提出了一种在量子网络中分布高保真的长距离纠缠的方法，该量子网络由网络节点之间的辅助短期路径提供的纠缠所提供的纠缠。以共享催化剂状态的形式的纠缠援助用于最大程度地提高网络边缘上的纠缠浓度转换的效率。将催化剂状态回收为用于网络节点的自适应操作，并使用辅助短距离路径定期补充。在没有使用纠缠援助的情况下，发现使用这种纠缠援助的远程纠缠分布的速率显着高于可能。
We propose an approach to distribute high-fidelity long-range entanglement in a quantum network assisted by the entanglement supplied by auxiliary short-range paths between the network nodes. Entanglement assistance in the form of shared catalyst states is utilized to maximize the efficiency of entanglement concentration transformations over the edges of the network. The catalyst states are recycled for use in adaptive operations at the network nodes and replenished periodically using the auxiliary short-range paths. The rate of long-range entanglement distribution using such entanglement assistance is found to be significantly higher than possible without using entanglement assistance.
