Quantum enhanced feedback cooling of a mechanical oscillator using nonclassical light

Real-time quantum feedback control can be used to cool quantum systems to their motional ground states, but this has been so far achieved via classical probe fields. Here the authors report feedback cooling of a mechanical oscillator using a squeezed field, reporting higher cooling rate over classic...

Summary:Real-time quantum feedback control can be used to cool quantum systems to their motional ground states, but this has been so far achieved via classical probe fields. Here the authors report feedback cooling of a mechanical oscillator using a squeezed field, reporting higher cooling rate over classical light.
