量子网络和信道的分布式仿真框架
A distributed simulation framework for quantum networks and channels
摘要：
我们介绍量子网络和通道模拟器（$\texttt{SQUANCH}$），这是一个开源Python库，用于创建分布式量子信息处理的并行模拟。该框架包括通用量子计算模拟器的许多功能，但它是专门为模拟量子网络而优化的。它包括允许用户轻松设计复杂的多方量子网络的功能，用于建模噪声量子信道的可扩展类，以及用于性能模拟的多处理NumPy后端。我们概述了库的结构，描述了各种API元素如何表示底层物理，并为每个模块提供了简单的使用示例。最后，我们提出了几个示范规范的量子信息协议使用这个框架实现。
英文摘要：
We introduce the Simulator for Quantum Networks and Channels ($\texttt{SQUANCH}$), an open-source Python library for creating parallelized simulations of distributed quantum information processing. The framework includes many features of a general-purpose quantum computing simulator, but it is optimized specifically for simulating quantum networks. It includes functionality to allow users to easily design complex multi-party quantum networks, extensible classes for modeling noisy quantum channels, and a multiprocessed NumPy backend for performant simulations. We present an overview of the structure of the library, describing how the various API elements represent the underlying physics and providing simple usage examples for each module. Finally, we present several demonstrations of canonical quantum information protocols implemented using this framework.
