论文摘要
长寿命的圆形Rydberg原子正在增加对基于Rydberg的量子模拟的相干时间的兴趣。我们详细阐述了一种新型方法，该方法是使用由二锡氧化物（ITO）薄膜制成的抑制电容器来稳定自发和黑体引起的衰变的方法，该膜结合了微波的反射和可见光谱范围的透明度。为此，我们使用GHz和THZ频率的互补光谱方法对此类膜进行了详细的表征，并确定允许在室温环境中达到多达数十毫秒的圆状寿命的条件。鉴于在室温下使用高$ n $圆形rydberg状态的量子模拟寻求量子模拟，我们讨论了我们的发现的前景。
Long-lived circular Rydberg atoms are picking up increasing interest for boosting coherence times in Rydberg-based quantum simulation. We elaborate a novel approach to stabilize circular Rydberg states against spontaneous and blackbody-induced decay using a suppression capacitor made from indium tin oxide (ITO) thin films, which combine reflection of microwaves with transparency in the visible spectral range. To this end, we perform detailed characterization of such films using complementary spectroscopic methods at GHz and THz frequencies and identify conditions that allow for reaching circular-state lifetimes up to tens of milliseconds in a room-temperature environment. We discuss prospects of our findings in view of the quest for quantum simulations with high-$n$ circular Rydberg states at room temperature.
