Fast Light Modulation for Ultracold Atoms
Ultracold atomic lattices are a hot platform for quantum information. By addressing neutral atoms with resonant light in an optical cavity we can induce effects like Rabi oscillations, Rydberg blockade, and many-body coherent interactions. Precise control over such effects enables exploration of complex Ising models, exotic spin liquids, and phase transitions. With the lifetime of our atoms being ~500 ms, however, the gate time (effective light modulation time) of our setup remains a key hurdle. Building on work from Thompson’s group, this project will enable sub-25µs gates on a new 2D optical lattice in the Ultracold group’s E6 experiment. This opens the door for a host of new features like atomic reloading, error correction, mid-circuit measurement, and exploration of 2D spin liquids and Bose-Hubbard models.
