我们使用量子网络的开源仿真包SeQUeNCe模拟线性链量子网络的两个端点节点之间的纠缠共享。我们的重点是具有有限量子存储寿命的多个中继器的终端节点之间的纠缠产生速率。数值和分析模拟表明，对于给定数量的中继器、内存寿命、终端节点之间的距离和纠缠管理协议，连接性能存在限制。我们的研究结果表明，量子连接的性能高度依赖于纠缠管理协议，该协议调度纠缠的产生和交换，从而导致最终的端到端纠缠。
We simulate entanglement sharing between two end-nodes of a linear chain quantum network using SeQUeNCe, an open-source simulation package for quantum networks. Our focus is on the rate of entanglement generation between the end-nodes with many repeaters with a finite quantum memory lifetime. Numerical and analytical simulations show limits of connection performance for a given number of repeaters involved, memory lifetimes, the distance between the end-nodes, and an entanglement management protocol. Our findings demonstrate that the performance of quantum connection depends highly on the entanglement management protocol, which schedules entanglement generation and swapping, resulting in the final end-to-end entanglement.
