Quantum information with multiplexed cavity-atom arrays

Cavities are a critical technology for neutral atom-based quantum networks; however they have proven difficult to interface with neutral atom arrays in a scalable manner. We have developed arrays of optical cavities which can be strongly coupled to an array of single atoms for readout and networking in a fast and parallel manner. Our system utilizes a new cavity geometry with intra-cavity lenses, taking advantage of the ability to achieve strong coupling via a wavelength-scale mode waist at moderate finesses. Here I will present our most recent progress towards demonstrating simultaneous trapping and detection of single atoms in our cavity array, and discuss the immediate applications of this system for quantum networking, simulation, metrology, and computing.
