基于纠缠的中继链网络中的保真度仿真

Simulation of fidelity in entanglement-based networks with repeater chains

David Pérez Castro, Ana Fernández Vilas, Manuel Fernández-Veiga, Mateo Blanco Rodríguez, Rebeca P. Díaz Redondo

AI总结:

本文基于 NetSquid 构建面向量子中继器与交换机路径的端到端保真度仿真环境,支持多寄存器、纠缠蒸馏、任意拓扑和精确退极化噪声,并比较顺序中继链与多寄存器交换机的性能。

摘要:

我们在 NetSquid 之上实现了一个仿真环境,专门用于估算跨越量子中继器或量子交换机路径的端到端保真度。该交换机模型包含若干目前其他工具尚不具备的通用化特性,这些特性有助于深入理解实际且现实的量子网络工程问题:交换机上任意数量的存储器寄存器、简便纳入纠缠蒸馏机制、任意交换拓扑,以及更精确的退极化噪声模型。文中给出了一个说明性案例研究,即比较两类方案的性能:一类是中继器只能按顺序进行交换的中继链,另一类是配备多个存储器寄存器、能够处理多个交换请求的单一交换机。

英文摘要:

We implement a simulation environment on top of NetSquid that is specifically designed for estimating the end-to-end fidelity across a path of quantum repeaters or quantum switches. The switch model includes several generalizations which are not currently available in other tools, and are useful for gaining insight into practical and realistic quantum network engineering problems: an arbitrary number of memory registers at the switches, simplicity in including entanglement distillation mechanisms, arbitrary switching topologies, and more accurate models for the depolarization noise. An illustrative case study is presented, namely a comparison in terms of performance between a repeater chain where repeaters can only swap sequentially, and a single switch equipped with multiple memory registers, able to handle multiple swapping requests.
