我们对两个开源量子网络模拟器 QuISP 和 SeQUeNCe 进行了比较分析，重点是对基本网络任务进行交叉验证，以确保模拟输出的一致性和准确性。尽管这两个模拟器都旨在研究量子网络管理策略及其在复杂噪声模型下的动态行为，但它们不同的底层假设可能导致模拟结果的差异。我们强调了这两个模拟器在处理连接、内部网络节点处理时间和经典通信方面的差异，这导致在执行基本网络任务（如纠缠生成、纯化和交换）所需的时间上出现显著的定量和定性差异。我们在模拟器之间模拟了常见场景，以比较资源分配的延迟和所分配资源的保真度。我们的研究结果表明，虽然模拟器在完成网络任务所需的时间上存在差异——这一常数因子差异归因于它们各自的连接模型——但在相同错误参数下，它们对所分配资源的保真度达成了一致。这项工作展示了朝着提高量子网络模拟的可靠性和可重复性迈出的关键第一步，并引领了完整协议的发展。此外，我们的基准测试方法为模拟器的交叉验证建立了一套基础任务，以研究未来的量子网络。
英文摘要
We present a comparative analysis of two open-source quantum network simulators, QuISP and SeQUeNCe, focusing on cross-validation of basic networking tasks to ensure consistency and accuracy in simulation outputs. Although both simulators are designed to study quantum network management policies and their dynamics under complex noise models, their differing underlying assumptions can lead to variations in simulation results. We highlight the discrepancies in how the two simulators handle connections, internal network node processing time, and classical communication, resulting in significant quantitative and qualitative differences in the time required to perform basic network tasks such as entanglement generation, purification, and swapping. We simulate common scenarios between the simulators to compare both the latency of resource distribution and the fidelity of the distributed resources. Our findings indicate that while the simulators differ in the time required to complete network tasks---a constant factor difference attributable to their respective connection models---they agree on the fidelity of the distributed resources under identical error parameters. This work demonstrates a crucial first step towards enhancing the reliability and reproducibility of quantum network simulations, as well as leading to full protocol development. Furthermore, our benchmarking methodology establishes a foundational set of tasks for the cross-validation of simulators to study future quantum networks.
