Abstract

In cavity opto-mechanical cooling, driving laser optical field, exerts extra decay to the mechanical mode of cavity, and cause a return to the ground state. In this study, quantum cooling of an opto-mechanical cavity in contact with a thermal bath, has been simulated by using Quantum Toolbox in Python “QuTiP”. Simulation results show that, the cavity cooling process, takes more time with increasing the decay rate of optical modes and go faster with increasing the decay rate of mechanical modes. Also this process takes less time with the increasing coupling constant of optical and mechanical modes. By adding a qubit to the system, simulation shows that the cooling process could happen faster in compare to the previous.
