• Abstract: We introduce wavefront shaping as a tool for optimizing the sensitivity in nano-optomechanical measurement schemes. We perform multimode output analysis of an optomechanical system consisting of a focused laser beam coupled to the transverse motion of a tapered cantilever, and demonstrate that wavefront shaping enables a 350-fold enhancement of the measurement signal-to-noise (+25.5 dB) compared to standard split-detection, close to the quantum precision limit. Our results open new perspectives in terms of sensitivity and control of the optomechanical interaction.

  We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
