Abstract

Levitated optomechanical systems are promising candidates for future quantum sensors due to their decoupling from the thermal environment. I will present recent results on optical and electric feedback cooling of a nanoparticle levitated in a Paul trap, as well as an approach for the efficient detection of the particle’s position based on self-homodyne; both of these topics can be understood as steps towards the quantum regime.
