论文摘要
朝着实现量子传感设备（例如Rydberg Atom电场传感器）的实现现实世界应用的关键步骤是减少其尺寸，重量，功率和成本（SWAP-C）要求，而没有大大降低性能。激光频率稳定是许多量子传感设备的关键部分，当用于令人兴奋的非地面状态原子过渡时，目前仅限于需要大型SWAP-C光学腔和电子设备的技术，或者仅利用重要的光学功率来稳定频率。在这里，我们描述了一种激动人心的非地面原子过渡的激光频率稳定技术，该跃迁解决了这些挑战，仅需要少量的额外电子设备。我们描述了该频率稳定技术的操作，功能和局限性，并定量地表征了其性能。我们通过实验表明，使用该技术的Rydberg电场传感器能够收集数据，同时仅牺牲了可用带宽的0.1％，以稳定噪声的频率稳定高达900 Hz。
A crucial step towards enabling real-world applications for quantum sensing devices such as Rydberg atom electric field sensors is reducing their size, weight, power, and cost (SWaP-C) requirements without significantly reducing performance. Laser frequency stabilization is a key part of many quantum sensing devices and, when used for exciting non-ground state atomic transitions, is currently limited to techniques that require either large SWaP-C optical cavities and electronics or use significant optical power solely for frequency stabilization. Here we describe a laser frequency stabilization technique for exciting non-ground state atomic transitions that solves these challenges and requires only a small amount of additional electronics. We describe the operation, capabilities, and limitations of this frequency stabilization technique and quantitatively characterize measure its performance. We show experimentally that Rydberg electric field sensors using this technique are capable of data collection while sacrificing only 0.1% of available bandwidth for frequency stabilization of noise up to 900 Hz.
