论文摘要
我们考虑在现有的光纤基础架构上部署量子网络的问题，在现有的光纤基础架构上，量子中继器和结束节点只能在特定位置容纳。我们提出了一种基于整数线性编程（ILP）的方法，以将中继器数量最少放在这种现有的网络拓扑上，以便满足任何一对节点之间的端到端纠缠产生速率和忠诚度的要求。尽管通常难以解决ILP，但我们表明我们的方法在最多100个节点的网络实践中表现良好。我们说明了方法在随机生成的网络拓扑以及荷兰部署的现实纤维拓扑上的行为。
We consider the problem of deploying a quantum network on an existing fiber infrastructure, where quantum repeaters and end nodes can only be housed at specific locations. We propose a method based on integer linear programming (ILP) to place the minimal number of repeaters on such an existing network topology, such that requirements on end-to-end entanglement-generation rate and fidelity between any pair of end-nodes are satisfied. While ILPs are generally difficult to solve, we show that our method performs well in practice for networks of up to 100 nodes. We illustrate the behavior of our method both on randomly-generated network topologies, as well as on a real-world fiber topology deployed in the Netherlands.
