Transfer of quantum correlations through strong coupling in a three-mode optomechanical system

In this paper, we investigate the generation of steady-state correlations through a three-mode optomechanical system. In particular, the hybrid system consists of two movable mirrors simultaneously coupled to a single cavity mode. We quantified the dynamics of the quantumness by logarithmic negativity, two non-Hermitian operators, and Gaussian quantum discord. Our results show that the transfer of correlations strongly depends on the physical parameters of the system. In particular, using the parameter regime the results show that a significant amount of quantum correlation is generated. Besides, the quantum discord between the optical and mechanical modes increases with drive laser power and decreases with mean thermal phonon number growths due to thermal noise causing decoherence. We further show that the transfer of quantum discord between the optical and mechanical modes can be controlled by adjusting the coupling strength. As a result, the effects of the other parameters are also discussed in detail. We believe that our results provide a good resource for the realization of quantum information processing.
