6.7 Conclusions

We have analyzed the three-mode optomechanical parametric interactions in the quantum picture. We have derived the quantum limit for cooling experiments with three-mode interactions based upon the Fluctuation-Dissipation-Theorem. We have shown the existence of tripartite quantum entanglements in this system. The simultaneous resonances of the carrier and sideband modes in the three-mode system allows more efficient mechanical-mode cooling and more robust optomechanical entanglement than in the two-mode system. This work provides the theoretical basis for the feasibility of realizing both ground-state cooling and stationary optomechanical quantum entanglements using three-mode optomechanical parametric interactions in small-scale table-top experiments and also large-scale GW interferometers.
