Towards deterministic entanglement generation in a new atom-cavity setup

The efficient and deterministic generation of entanglement in a manybody system poses a challenge for analog and digital quantum simulators. While atomic platforms provide great scalability, they mostly rely on local couplings, for instance, collisional or Rydberg interactions. We report on the current status of a new experimental apparatus to strongly couple an atomic tweezer array to a fiber-based Fabry-Pérot cavity. The cavity geometry with short length, small mirror diameter, and large curvature, places us in a unique regime with simultaneously high single-atom cooperativity and single-atom addressing and readout. Our setup is optimized for fast repetition rates, owing to loading the tweezer array from a magneto-optical trap which is placed within millimeters from the cavity. In future, harnessing this new control will enable us to engineer entanglement through photon-mediated interactions. Further advantages of this platform include partial nondestructive readout and efficient multi-qubit entanglement operations. In the long term, the proposed platform provides a scalable path to studying many-body systems with programmable connectivity, as well as an efficient atom-photon interface for quantum communication applications.
