论文摘要
超出强大的单个原子腔耦合制度之外的高质量特殊非经典状态的实现是量子信息科学中的基本要素。在这里，我们研究了单个旋转1原子中的非经典光子发射，并通过构建Spin-1 Jaynes-Cummings模型耦合到光腔。通过调整二次zeeman偏移，可以随着良好解决的N-Photon共振的穿着状态分裂而显着增强能量光谱的非谐调性。光子发射分别在空腔和原子驱动的病例中表现出高质量的单光子和两光子束性能。更有趣的是，非经典的光学切换从强大的单光子阻滞到两光子束和超级波索尼亚光子发射，并且可以通过在原子和空腔驱动场的存在下通过轻型腔内失调而高度控制。我们的建议不仅为产生高质量的N-光子来源开辟了新的途径，而且还提供了量子网络和量子计量学中的多功能应用程序。
The realization of high-quality special nonclassical states beyond strong single atom-cavity coupling regime is a fundamental element in quantum information science. Here, we study the nonclassical photon emission in a single spin-1 atom coupled to an optical cavity with constructing a spin-1 Jaynes-Cummings model. By tuning quadratic Zeeman shift, the energy-spectrum anharmonicity can be significantly enhanced with respect to the dressed-state splitting of well-resolved n-photon resonance largely increased. The photon emission exhibit high-quality single photon and two-photon bundles properties with large photon numbers in the cavity and atom driven cases, respectively. More interestingly, nonclassical optical switching from strong single-photon blockade to two-photon bundles and super-Poissonian photon emission is achieved and highly controllable by light-cavity detuning in the presence of both atom and cavity driven fields. Our proposal not only open up a new avenue for generating high-quality n-photon sources but also provide versatile applications in quantum networks and quantum metrology.
