Optical squeezing for an optomechanical system without quantizing the mechanical motion

Witnessing quantumness in mesoscopic objects is an important milestone for both quantum technologies and foundational reasons.Cavity optomechanics offers the ideal system to achieve MAKE UP REMOVERS this by combing high-precision optical measurements with mechanical oscillators.However, mechanical quantumness can only be established if the behavior is incompatible with any classical description of an oscillator.After explicitly considering classical and hybrid quantum-classical Heat Sink descriptions of an optomechanical system, we rule out squeezing of the optical field as such a witness by showing it is also predicted without quantizing the mechanical oscillator.
