A quantum correlation between two coupled hybrid optomechanical cavities is evaluated by quantifying the non-classical correlation using Gaussian quantum discord. In our mathematical treatment, we solve and analyze the quantum Langevin equations and the corresponding covariance matrix of the system, respectively. We show that the generation of quantum correlation and its robustness essentially depend on the physical parameters of the system. Based on the experimentally realizable conditions and using the Ruths-Hurwitz criterion, we perform a stability analysis and confirm the quantum discord dynamics.
