We proposed a new method to optically levitate a mirror with two vertical Fabry-Perot cavities linearly aligned. With this configuration, we showed that both stable levitation and reaching the standard quantum limit of a milligram scale mirror are experimentally feasible with current technology. We also worked on the proof of principle experiment with a torsion pendulum to demonstrate the stability of our new configuration.If we can realize the optical levitation with the proposed setup, we can realize a quantum entanglement between the positions of two macroscopic mirrors much heavier than the Planck mass. Our research paves the way to experimentally answer the fundamental question of the validity of quantum mechanics in macroscopic scales.
