AI 中文摘要
光学腔中的强原子-光子相互作用是量子信息处理、量子网络及量子光学效应探索的关键资源。光镊阵列可实现中性原子的可扩展、位点分辨控制，但其与高协同度腔量子电动力学（cavity QED）系统的集成仍具挑战。本研究将12位点的⁸⁷Rb光镊阵列与高协同度光纤法布里-珀罗微腔结合，阵列被置于腔模内，各单一位点以亚波长精度控制，可通过驻波场的确定性位移连续调控单原子耦合强度。针对最多5个耦合到腔的原子，实验测量了集体增强的真空拉比分裂，并实现了基于腔的耦合原子数非破坏性读出。这些结果构建了可扩展的腔介导纠缠产生架构及具备单原子控制的多体腔量子电动力学，为光纤集成量子网络节点奠定了基础。
英文摘要
Strong atom-photon interactions in optical cavities are a key resource for quantum information processing, quantum networking, and the exploration of quantum optical effects. Optical tweezer arrays offer scalable, site-resolved control of neutral atoms, but their integration with high-cooperativity cavity QED systems remains challenging. Here we combine a twelve-site $^{87}$Rb optical tweezer array with a high-cooperativity fiber Fabry-Pérot microcavity. The array is positioned within the cavity mode and individual sites are controlled with subwavelength precision, enabling continuous tuning of the single-atom coupling strength via deterministic displacement through the standing-wave field. For up to five atoms coupled to the cavity, we measure collectively enhanced vacuum Rabi splitting and implement cavity-based non-destructive readout of the number of coupled atoms. These results establish a scalable architecture for cavity-mediated entanglement generation and many-body cavity QED with single-atom control, and they lay the foundation for fiber-integrated quantum network nodes.
