控制光子统计特性对于经典和量子光子学中的许多应用至关重要。虽然稳态光子统计已被广泛研究，但在时间上动态操控这些统计特性仍然难以实现。在此，我们提出一种通过量子干涉主动控制光子统计在聚束和反聚束区域之间切换的方案。我们的方法依赖于一个具有参量放大作用的拉曼耦合腔-原子系统，其中对中间态失谐的时间调制使我们能够加深光子阻塞或增强光子聚束。同时调制腔和中间态失谐可产生在静态条件下或单独调制任一失谐时无法实现的反聚束效应。由于调制是周期性的，反聚束会在规则时间间隔内重新出现，从而在连续波操作下实现时间门控的光子反聚束，其重复率由调制频率决定。这些结果表明，基于拉曼辅助量子干涉的通用机制可用于动态调控光子关联。
英文摘要
Controlling photon statistics is pivotal to many applications in classical and quantum photonics. While steady-state photon statistics have been widely studied, dynamically manipulating these statistical properties in time remains elusive. Herein, we propose a scheme to actively control photon statistics between bunching and antibunching regimes through quantum interference. Our approach relies on a Raman-coupled cavity-atom system with parametric amplification, where time modulating the detuning of the intermediate state allows us to either deepen the photon blockade or enhance photon bunching. Simultaneous modulation of the cavity and intermediate-state detunings produces antibunching that cannot be achieved under static conditions or by modulating either detuning alone. Because the modulation is periodic, the antibunching reappears at regular time intervals, enabling time-gated photon antibunching under continuous-wave operation at a repetition rate determined by the modulation frequency. These results show a versatile mechanism based on Raman-assisted quantum interference for dynamically engineering photon correlations.
