摘      要：The optically levitated object is intrinsically isolated from the thermal bath compared with the opto-mechanical oscillator connected to the thermal environment via the cantilever [1,2]. Thus the limitation of the thermalization and decoherence in- troduced by the cantilever is cancelled. The Q-factor of the system is predicted to approach 1012 and the system is extremely sensitive to some changes [3-6]. And it is expected to detect non-Newtonian gravity forces at very small scales [7], the impact of single air molecules [8], nanoscaie temperature [9], and magnetic spin resonance [10]. Importantly it can be used to test the fundamental physical problems.
