AI 中文摘要
基于腔量子电动力学的量子技术面临的一个核心挑战是使高协同性光学界面与单原子的位点分辨阵列兼容。在此，我们展示了在光纤法布里 - 珀罗微腔内的单个\(^{87}\)Rb原子的光镊阵列，单原子协同性\(\mathcal{C} \sim 90\)。我们将扩展阵列的无背景位点分辨荧光成像与平均原子数高达\(\bar{N} \simeq 36\)的阵列到公共腔模的集体耦合相结合。这些结果为具有位点分辨检测和控制的多体腔量子电动力学建立了一个高协同性平台。
英文摘要
A central challenge for cavity-QED-based quantum technologies is to make high-cooperativity optical interfaces compatible with site-resolved arrays of single atoms. Here, we demonstrate optical tweezer arrays of individual $^{87}$Rb atoms inside a fiber Fabry-Perot microcavity with single-atom cooperativity $\mathcal{C} \sim 90$. We combine background-free site-resolved fluorescence imaging of extended arrays with collective coupling to a common cavity mode for arrays with a mean atom number up to $\bar{N} \simeq 36$. These results establish a high-cooperativity platform for many-body cavity-QED with site-resolved detection and control.
