一种用于量子光学实验的可扩展自分析数字锁定系统
A Scalable, Self-Analyzing Digital Locking System for use on Quantum Optics Experiments
摘要：
与模拟控制系统相比，光学实验的数字控制具有许多优势，特别是在可扩展性，成本，灵活性以及将系统信息集成到一个位置方面。我们提出了一个数字控制系统，可免费在线下载，专门为量子光学实验设计，允许自动和顺序重新锁定光学组件。我们展示了如何使用内置的锁定分析工具（包括白噪声网络分析仪）来帮助优化单个锁定，并验证数字系统的长期稳定性。最后，我们提出了一个例子，数字锁定量子光学的好处，通过应用代码的一个特定的实验用于表征光学薛定谔猫态。
英文摘要：
Digital control of optics experiments has many advantages over analog control systems, specifically in terms of scalability, cost, flexibility, and the integration of system information into one location. We present a digital control system, freely available for download online, specifically designed for quantum optics experiments that allows for automatic and sequential re-locking of optical components. We show how the inbuilt locking analysis tools, including a white-noise network analyzer, can be used to help optimize individual locks, and verify the long term stability of the digital system. Finally, we present an example of the benefits of digital locking for quantum optics by applying the code to a specific experiment used to characterize optical Schrodinger cat states.
