mechanical resonators for quantum-enhanced sensing
project will capitalize on the exquisite isolation of a magnetically levitated,
micrometer-sized superconducting particle and its coupling to superconducting
circuits. This unique experimental platform should be capable of enabling
quantum control over the center-of-mass motion of the levitated particle. The
particle displacement is sensitive to small forces or accelerations, which
makes this platform suitable as a novel quantum-enhanced sensor.
