Strong atom–photon interactions in optical cavities provide a key resource for cavity-mediated many-body physics, quantum information processing, and quantum networking. Optical tweezer arrays offer scalable, site-resolved control of neutral atoms, but their integration with high-cooperativity cavity QED systems has been an outstanding challenge. I will report on our recent experiments, where we achieve this long-standing goal. The setup integrates three ingredients: single atom control for arbitrary quantum logical operations, a tweezer-cavity system for cavity QED, and a fiber interface for real-time measurements. Our results open a path to programmable interactions within an atomic tweezer array, to non-destructive readout protocols, and to implementing quantum network protocols.
