量子光力学将光力可以实现机械运动的量子控制的思想扩展到介观和宏观系统。在对冷阻尼和光学弹簧效应进行半经典介绍之后，我们展示了边带冷却如何使这些系统达到量子力学基态。然后我们讨论准备、操纵和表征机械振荡器的其他量子态的方法。接下来是对光机械干涉仪的标准量子极限的分析，阐明了散粒噪声和辐射压力噪声的作用。我们最终回到超冷原子，以展示它们的集体密度激发如何同样充当光机械振荡器。
Quantum optomechanics extends the idea that light forces can achieve the quantum control of mechanical motion to mesoscopic and macroscopic systems. Following a semiclassical introduction to cold damping and the optical spring effect, we show how sideband cooling can bring those systems to their quantum mechanical ground state. We then discuss ways to prepare, manipulate, and characterize other quantum states of mechanical oscillators. This is followed by an analysis of the standard quantum limit of optomechanical interferometers that clarifies the roles of shot noise and radiation pressure noise. We finally return to ultracold atoms to show how their collective density excitations can likewise behave as optomechanical oscillators.
