论文摘要
探测古典和量子力学之间的边界一直是现代物理学中的中心主题之一。最近，精确测量具有光腔量振荡器的力的实验吸引了一种有希望的工具来测试量子力学，变形机制和引力物理学的有前途的工具。在本文中，我们回顾了使用毫克量表的光学机械系统的实验现状。我们比较以摆，扭转的摆和光学悬浮的镜子来达到量子状态的可行性。设计高$ q $ pendulum的考虑因素，扭转摆的条件比摆锤具有更好的力敏感性，并提出了设计镜子光学悬浮的限制。
Probing the boundary between classical and quantum mechanics has been one of the central themes in modern physics. Recently, experiments to precisely measure the force acting on milligram scale oscillators with optical cavities are attracting interest as promising tools to test quantum mechanics, decoherence mechanisms, and gravitational physics. In this paper, we review the present status of experiments using milligram scale optomechanical systems. We compare the feasibility of reaching the quantum regime with a pendulum, torsion pendulum, and optically levitated mirror. Considerations for designing a high $Q$ pendulum, condition for torsion pendulums to have better force sensitivity than pendulums, and constraints in designing optical levitation of a mirror are presented.
