State Preparation: Non-Gaussian Quantum State

Abstract

As we conclude from the previous chapter, in order to create non-Gaussian quantum states, a nonlinear optomechanical coupling is generally required. This is rather challenging to achieve, especially when the mass of the mechanical oscillator is large and the frequency is low. In this chapter, we propose a protocol for coherently transferring non-Gaussian quantum states from the optical field to a mechanical oscillator, which does not require a nonlinear coupling in the optomechanical system.
