标题： SimOS: A Python Framework for Simulations of Optically Addressable Spins

摘要： 我们提出一个用于光学检测磁共振的开源仿真框架，该框架使用Python开发。 该框架允许用户构建、操作和演化由自旋和电子能级组成的多部分量子系统。 我们提供了一个用于Lindblad形式高效时间演化的接口，以及一个促进空间和广义随机动力学仿真的框架。 此外，还支持简单模型系统的符号算子构建和传播，使该框架也适用于磁共振课程教学。 设计为后端无关，该库利用现有的Python库作为计算后端。 我们介绍了最重要的功能，并通过一系列示例说明语法。 这些示例包括如金刚石中的氮空位中心和光生自旋关联自由基对等系统，我们的库为这些系统提供了特定的子模块。 显示英文摘要

摘要： We present an open-source simulation framework for optically detected magnetic resonance, developed in Python. The framework allows users to construct, manipulate, and evolve multipartite quantum systems that consist of spins and electronic levels. We provide an interface for efficient time-evolution in Lindblad form as well as a framework for facilitating simulation of spatial and generalized stochastic dynamics. Further, symbolic operator construction and propagation is supported for simple model systems making the framework also ideal for use in classroom instruction of magnetic resonance. Designed to be backend-agnostic, the library leverages existing Python libraries as computational backends. We introduce the most important functionality and illustrate the syntax on a series of examples. These include systems such as the nitrogen-vacancy center in diamond and photo-generated spin-correlated radical pairs for which our library offers system-specific sub-modules.
