• Abstract summary: We show that laser recoil can be arbitrarily suppressed by shining squeezed light onto an optically trapped nanoparticles. We analyze the trade-off between measurement imprecision and back-action noise. We predict that, with state-of-the-art squeezed light sources, laser heating can be reduced by at least 60%.

• Abstract: We theoretically show that laser recoil heating in free-space levitated optomechanics can be arbitrarily suppressed by shining squeezed light onto an optically trapped nanoparticle. The presence of squeezing modifies the quantum electrodynamical light-matter interaction in a way that enables us to control the amount of information that the scattered light carries about a given mechanical degree of freedom. Moreover, we analyze the trade-off between measurement imprecision and back-action noise and show that optical detection beyond the standard quantum limit can be achieved. We predict that, with state-of-the-art squeezed light sources, laser recoil heating can be reduced by at least 60% by squeezing a single Gaussian mode with an appropriate incidence direction, and by 98% by squeezing a properly mode-matched mode. Our results, which are valid both for motional and librational degrees of freedom, will lead to improved feedback cooling schemes as well as boost the coherence time of optically levitated nanoparticles in the quantum regime.

New insights on the underlying physical decoherence mechanisms reveals a limit in temperature until which coherent driving of the system is possible.
