Macroscopic quantumness in optically conditioned mechanical systems

Activity: Talk or presentation typesInvited talk


In optomechanical systems, conditional measurements on the optical mode can be used to engineer states of the mechanical mode. In this talk, I discuss the effect that measurement settings have on the macroscopic quantumness of the mechanical mode. The measure used is based on phase-space methods (Phys. Rev. Lett. 106, 220401 (2011)). The aim of the project is to find protocols which optimise mechanical macroscopicity. Additionally, I evaluate the effect of losses for the case of an open cavity and analyze the impact on the features of the Wigner function of the mechanical state.
