Optomechanics with levitated subwavelength dielectric nanoparticles(NPs) has attracted strong interest since its conception.Good isolation of the mechanical motion from the environment and therelatively high mass of the NPs make these systems especially suitablefor wide applications, including quantum sensing and fundamentalphysics tests.Inspired by the recent achievements of Gaussian control of the NPs'motion, we consider theoretically the prospects of reachingnon-classical and eventually quantum non-Gaussian states of theirmotion.In this talk, we will start with a general introduction to the fieldof optomechanics, with an emphasis on the peculiarities of thelevitated NPs.We will then consider a protocol to generate optomechanicalentanglement via pulsed two-mode squeezing interaction, and aprocedure to enhance the entanglement using Bayesian optimization ofthe control parameters.
