基于对Paul阱中单个离子运动的实时测量，我们通过零差反馈控制（冷阻尼）证明了其在多普勒极限以下的机电冷却。基于量子力学主方程的模型很好地描述了反馈冷却的结果。
Based on a real-time measurement of the motion of a single ion in a Paul trap, we demonstrate its electromechanical cooling below the Doppler limit by homodyne feedback control (cold damping). The feedback cooling results are well described by a model based on a quantum mechanical master equation.
