Small-Waist Cavities Part 2: Towards Cavity Tweezer Arrays

Fast, non-destructive, parallel readout of atom arrays is key for the implementation of mid-circuit measurement, effective quantum error-correcting codes and quantum repeater schemes. At present, most atom-imaging schemes require millisecond timescales or are destructive. We have expanded the design of our sub-micron waist optical resonator to an array of over 100 independent cavities that can couple to an atom array with 3-8um spacing. With this design we expect to achieve single atom cooperativities between 5 and 10. We introduce the design parameters of this cavity array and summarize recent progress locking and loading single atoms into it. Finally, we discuss prospects for interfacing with tweezers array platforms and harnessing our approach as a high bandwidth quantum repeater.
