Loading and Imaging Atom Arrays via Electromagnetically Induced Transparency

Arrays of neutral atoms present a promising system for quantum computing, quantum sensors, and other applications, several of which would profit from the ability to load, cool, and image the atoms in a finite magnetic field. In this work, we develop a technique to image and prepare ⁸⁷Rb atom arrays in a finite magnetic field by combining EIT cooling with fluorescence imaging. We achieve 99.6(3)% readout fidelity at 98.2(3)% survival probability and up to 68(2)% single-atom stochastic loading probability. We further develop a model to predict the survival probability, which also agrees well with several other atom array experiments. Our technique cools both the axial and radial directions, and will enable future continuously-operated neutral atom quantum processors and quantum sensors.
