Photon-mediated interactions are a powerful tool for realizing multi-particle entanglement and long-range interacting Hamiltonians. They have been studied both in systems with collectively coupled atomic ensembles, and with strongly coupled few-body systems. However, creating photon-mediated interactions in larger systems with single-atom control remains challenging. We report on our current progress towards an atomic tweezer array that is strongly coupled to an optical fiber cavity. The setup combines single-atom control with photon-mediated interactions in the strong coupling regime, and it includes a real-time measurement channel through the optical fiber. This opens a path for programmable interactions within an atomic tweezer array, for non-destructive readout protocols, and to implement dissipative state preparation schemes.
