@article{Rakhubovsky2019StroboscopicHN, title={Stroboscopic high-order nonlinearity for quantum optomechanics}, author={Andrey A. Rakhubovsky and Radim Filip}, journal={npj Quantum Information}, year={2019}, volume={7}, pages={1-7} }

High-order quantum nonlinearity is an important prerequisite for the advanced quantum technology leading to universal quantum processing with large information capacity of continuous variables. Levitated optomechanics, a field where motion of dielectric particles is driven by precisely controlled tweezer beams, is capable of attaining the required nonlinearity via engineered potential landscapes of mechanical motion. Importantly, to achieve nonlinear quantum effects, the evolution caused by the… Expand
