| contents | We develop a general theoretical framework for characterizing stable quantum resources between microwave and optical modes in the dynamics of multipartite hybrid quantum systems with intermediary modes. The effective Hamiltonian for microwave-optical (MO) squeezing is formulated via strong interactions in the microwave-intermediary-optical hybrid system, and based on which rigorous solutions for the dynamics of MO entanglement and quantum steering are derived analytically. Remarkably, it is found that stable MO quantum resources can survive in the unsteady evolution beyond the steady one, and the unsteady evolution can exhibit the enhanced quality over the limit of quantum resources in the steady-state case. Furthermore, the stable MO entanglement as well as one-way and two-way quantum steerings are efficiently controllable by modulating the effective coupling strength. The validity of our theory is demonstrated by applying it to the typical models of electro-optomechanical and cavity optomagnomechanical hybrid systems. |
