标题： Simulation of entanglement based quantum networks for performance characterization

摘要： 基于纠缠的网络（EBNs）通过结合纠缠及其交换序列，实现了通用量子通信，解决了与量子技术相关的长距离通信高保真度挑战。 在此背景下，纠缠分发指的是量子网络中两个节点共享一个纠缠态的过程，这是通信的基本资源。 在本文中，我们研究了在由终端节点和量子交换机组成的物理拓扑上纠缠分发机制的性能，这些是构建大规模链路的关键。 为此，我们在NetSquid中实现了一个基于交换机的拓扑，并进行了一系列仿真实验，以深入了解实际和现实的量子网络工程挑战。 这些挑战一方面涉及量子技术方面的问题，如存储技术、门操作时间以及噪声；另一方面涉及分发过程相关因素，如交换机数量、距离、纯化和纠错。 所有这些因素都会显著影响路径上的端到端保真度，这支持两个量子节点之间的通信。 我们利用这些实验得出了一些未来EBNs设计和配置的指导原则。 显示英文摘要

摘要： Entanglement-based networks (EBNs) enable general-purpose quantum communication by combining entanglement and its swapping in a sequence that addresses the challenges of achieving long distance communication with high fidelity associated with quantum technologies. In this context, entanglement distribution refers to the process by which two nodes in a quantum network share an entangled state, serving as a fundamental resource for communication. In this paper, we study the performance of entanglement distribution mechanisms over a physical topology comprising end nodes and quantum switches, which are crucial for constructing large-scale links. To this end, we implemented a switch-based topology in NetSquid and conducted a series of simulation experiments to gain insight into practical and realistic quantum network engineering challenges. These challenges include, on the one hand, aspects related to quantum technology, such as memory technology, gate durations, and noise; and, on the other hand, factors associated with the distribution process, such as the number of switches, distances, purification, and error correction. All these factors significantly impact the end-to-end fidelity across a path, which supports communication between two quantum nodes. We use these experiments to derive some guidelines towards the design and configuration of future EBNs.
