Abstract: Neutral atom quantum processors can greatly benefit from integration with optical cavities. These optical interfaces can be used for fast readout for real time error detection and as a quantum networking node to entangle distant quantum processors. Here we present one candidate for such integration: a Fabry-Perot Fiber Cavity (FPFC). This system is compatible with optical tweezer arrays and enables strong coupling of multiple atoms with a single cavity mode. We cool and trap single atoms in optical tweezers above the FPFC and transport them into the cavity mode where we measure a single atom cooperativity greater than 100. We explore the capabilities of the platform with single and two atom experiments, demonstrating high fidelity readout and novel cavity-mediated gates. This work paves the way towards integration of FPFCs with atom arrays for quantum computation, simulation, and networking protocols.
