Strong mechanical squeezing for a levitated particle by coherent scattering

Levitated particles are a promising platform for precision sensing of external perturbations and probing the boundary between quantum and classical worlds. A critical obstacle for these applications is the difficulty of generating nonclassical states of motion which have not been realized so far. He...

description Levitated particles are a promising platform for precision sensing of external perturbations and probing the boundary between quantum and classical worlds. A critical obstacle for these applications is the difficulty of generating nonclassical states of motion which have not been realized so far. Here, we show that strong squeezing of the motion of a levitated particle below the vacuum level is feasible with available experimental parameters. Using suitable modulation of the trapping potential (which is impossible with clamped mechanical resonators) and coherent scattering of trapping photons into a cavity mode, we explore several strategies to achieve strong phase-sensitive suppression of mechanical fluctuations. We analyze mechanical squeezing in both transient and steady-state regimes, and discuss conditions for preparing nonclassical mechanical squeezing. Our results pave the way to full, deterministic optomechanical control of levitated particles in the quantum regime.
