“…Finally, all of the physics we have considered has been focused on measuring collective observables of the system (in the appropriate frame). State-of-the-art tools like optical tweezers and quantum gas microscopes for AEAs allow for the preparation and site-resolved measurement of quench dynamics for non-uniform initial states [60][61][62][63]. This would allow to probe for example the collisional properties of multi-atom objects undergoing different types of interaction-enabled and/or direct (dressed spin-conserving) motion in a spatially resolved fashion.…”

“…Speed limits imposed by the need to transport atoms into the cavity prior to measurement could be improved by employing optical-latticebased conveyors [43]. Transport could be eliminated altogether by maintaining the tweezer array entirely within the cavity volume and using rapid ac Stark shifts realized with local illumination to bring atoms selectively into resonance with the cavity for detection [18]. The atom loss probability could be reduced by using real-time processing and an adaptive measurement that stops each probe interval when a measurement outcome is obtained, and also by applying laser cooling briefly after detection.…”

The non-destructive measurement of a subsystem within a larger quantum system is crucial for error correction during quantum computation, simulation, and metrology, and for studying open quantum system dynamics. In many quantum technologies based on trapped atoms, measurement is performed by imaging all atoms simultaneously, a process that is typically slow and that decoheres the entire quantum system. Here, we use a strongly coupled optical cavity to read out the state of a single tweezer-trapped 87 Rb atom within a small tweezer array. Measuring either atomic fluorescence or the transmission of light through the cavity, we detect both the presence and the state of an atom in the tweezer, requiring only tens of microseconds for state-selective detection, with state preparation and measurement infidelities of roughly 0.5% and atom loss probabilities of around 1%. Using a two-tweezer system, we find measurement on one atom within the cavity causes no observable hyperfine-state decoherence on a second atom located tens of microns from the cavity volume.
