光学干涉计量学长期以来一直是表征光的量子态的一种方法。线性和非线性干涉都可以提供关于光统计和光-物质相互作用的基本细节的信息。在这里，我们演示了如何使用非线性光谱信号的干涉检测来提高物质磁化率的测量精度。光与物质的相互作用改变了量子光的光子统计，这些统计信息编码在场关联函数中。应用于Hong-Ou-Mandel双光子干涉仪，揭示了现有光学技术可以达到的纠缠增强的分辨率。
Optical interferometry has been a long-standing setup for characterization of quantum states of light. Both linear and the nonlinear interferences can provide information regarding the light statistics and underlying detail of the light-matter interactions. Here we demonstrate how interferometric detection of nonlinear spectroscopic signals may be used to improve the measurement accuracy of matter susceptibilities. Light-matter interactions change the photon statistics of quantum light, which are encoded in the field correlation functions. Application is made to the Hong-Ou-Mandel two-photon interferometer that reveals entanglement-enhanced resolution that can be achieved with existing optical technology.
