论文摘要
光力学系统正迅速成为观察量子行为的最有希望的平台之一，尤其是在宏观水平上。此外，由于其最新的制造方法，它们现在可能会在其组成的机械和光学自由度之间进入非线性相互作用的制度。在这项工作中，我们展示了这种新型机会如何构建新一代的光力传感器。我们考虑了基于从空腔泄漏的光子计数的检测方案的规范光学机械设置。通过进行模拟并诉诸贝叶斯推断，我们证明了检测到的光子的非古典相关性可能会实时增强传感器的性能。我们认为，我们的工作可能会刺激此类设备设计的新方向，而我们的方法也适用于利用非线性光 - 摩擦相互作用和光子检测的其他平台。
Optomechanical systems are rapidly becoming one of the most promising platforms for observing quantum behaviour, especially at the macroscopic level. Moreover, thanks to their state-of-the-art methods of fabrication, they may now enter regimes of non-linear interactions between their constituent mechanical and optical degrees of freedom. In this work, we show how this novel opportunity may serve to construct a new generation of optomechanical sensors. We consider the canonical optomechanical setup with the detection scheme being based on time-resolved counting of photons leaking from the cavity. By performing simulations and resorting to Bayesian inference, we demonstrate that the non-classical correlations of the detected photons may crucially enhance the sensor performance in real time. We believe that our work may stimulate a new direction in the design of such devices, while our methods apply also to other platforms exploiting non-linear light-matter interactions and photon detection.
