In work towards Rydberg-dressing quantum computation, we demonstrate hyperfine state readout of individual Cesium atoms in optical tweezers with ≤ 0.7(2)% infidelity and low loss. After further study of relevant atom-photon interaction physics, we obtain this result via adaptive measurement and careful choice of detection parameters to minimize depumping and heating. Our techniques impose no stringent vacuum or optical requirements and can be readily adopted to improve detection on similar systems.
