Schleier-Smith's group uses optical-cavity-mediated interactions to entangle and spin-squeeze ensembles of trapped neutral atoms, generating metrologically useful entangled states for quantum-enhanced sensing, and is developing modular, networked atom-cavity systems as building blocks for distributed quantum sensor arrays and simulators.

PREFERRED. Vuletic's group generates large-scale spin squeezing and entanglement in cold and ultracold atomic ensembles to push optical atomic clocks and rotation/field sensors below the standard quantum limit, alongside work on cavity QED, Rydberg tweezer arrays, and nonlinear quantum optics at the single-photon level. Recent work includes cavity-feedback spin squeezing for ytterbium clocks and fault-tolerant neutral-atom quantum sensor/processor arrays with collaborators at Harvard.
