几个光力学实验现在正进入高度追求的非线性状态，即使在低光水平下，光力学相互作用也很大。在这种情况下，可能会实现新的量子现象和改进的性能；然而，需要一个相应的腔量子光力学的理论形式来捕捉辐射-压力相互作用和腔响应的非线性，以解锁这些能力。在这里，我们开发了这样一个非线性腔量子光力学框架，然后我们利用它来提出如何在线性化近似分解之后进行位置测量。我们的建议利用光通用差检测，范围从单到双零差，以获得机械位置信息印在光振幅和相位正交上，并支持脉冲和连续操作模式。这些空腔光力学非线性现在正面临着越来越多的实验，我们的框架将允许一系列的进步，例如，量子计量，探索标准量子极限，量子测量和控制。
Several optomechanics experiments are now entering the highly sought nonlinear regime where optomechanical interactions are large even for low light levels. Within this regime, new quantum phenomena and improved performance may be achieved; however, a corresponding theoretical formalism of cavity quantum optomechanics that captures the nonlinearities of both the radiation-pressure interaction and the cavity response is needed to unlock these capabilities. Here, we develop such a nonlinear cavity quantum optomechanical framework, which we then utilize to propose how position measurement can be performed beyond the breakdown of the linearized approximation. Our proposal utilizes optical general-dyne detection, ranging from single to dual homodyne, to obtain mechanical position information imprinted onto both the optical amplitude and phase quadratures and enables both pulsed and continuous modes of operation. These cavity optomechanical nonlinearities are now being confronted in a growing number of experiments, and our framework will allow a range of advances to be made in, e.g., quantum metrology, explorations of the standard quantum limit, and quantum measurement and control.
