A 600-site cavity array microscope for parallel single-atom interfacing

ORAL

Abstract

Optical cavities are a foundation technology for controlling light-matter interactions. While interfacing a single cavity to either an atom or ensemble has become a standard tool, the advent

of single atom control in large atomic arrays has spurred interest in a new frontier of “many-cavity QED,” featuring many independent resonators capable of separately addressing individual

quantum emitters. In this fast-evolving landscape, the cavity array microscope was recently introduced—employing free space intra-cavity optics to engineer a two-dimensional array of tightly

spaced cavity TEM00 modes with wavelength-scale waists, ideally suited for interfacing with atom arrays. In this talk I will discuss our recent results coupling arrays of single atoms to these systems, as well as our next-generation architecture where we achieve hundreds of degenerate cavity modes with improved, uniform finesse. Finally, I will elaborate on the design heuristics we have uncovered which illuminate a direct pathway towards operation with tens of thousands of independent cavities with compatibility with existing atom arrays, paving the way to myriad applications including highly parallelized remote entanglement generation, fast and non-destructive mid-circuit readout, and the implementation of hybrid atom-photon Hamiltonians.
