论文摘要
从简单的量子系统和经典资源中创建非古典光状态是一个具有挑战性的问题。我们展示了连贯驱动下的手性发射器如何产生非经典光子状态。为了进行分析，我们在传输光场中选择一个特定的时间模式，从而为相关模式和手性发射器提供了耦合的主方程。我们通过其Wigner函数来表征该模式的状态，并表明系统的发射主要产生少量增添相干状态的混合物。我们认为这些非古典状态在实验上可以访问，并显示了它们在量子计量学上的应用。
Creating non-classical states of light from simple quantum systems together with classical resources is a challenging problem. We show how chiral emitters under a coherent drive can generate non-classical photon states. For our analysis, we select a specific temporal mode in the transmitted light field, resulting in a coupled master equation for the relevant mode and the chiral emitters. We characterise the mode's state by its Wigner function and show that the emission from the system predominantly produces mixtures of few-photon-added coherent states. We argue that these non-classical states are experimentally accessible and show their application for quantum metrology.
