AI总结:

本研究针对n光子Jaynes-Cummings模型,利用近共振强驱动使系统工作于Mollow区产生超拉比振荡,通过多种关联函数与量子轨迹验证了多光子束发射,为多光子量子器件研究奠定基础。

摘要:

我们研究了由二能级系统通过$n$光子激发过程耦合到单模光场构成的$n$光子Jaynes-Cummings模型中的多光子束发射现象。这里,二能级系统受到近共振单色场的强驱动,因此系统可工作在Mollow区,在适当的共振条件下,零光子态和$n$光子态之间会发生超拉比振荡。我们计算了光子数布居和标准的等时高阶关联函数,发现该系统中可以发生多光子束发射。通过研究态布居的量子轨迹以及多光子束的标准和广义时延二阶关联函数,也证实了多光子束发射的存在。我们的工作为多光子量子相干器件的研究铺平了道路,在量子信息科学与技术中具有潜在应用价值。

英文摘要:

We study the multiple-photon bundle emission in the $n$-photon Jaynes-Cummings model composed of a two-level system coupled to a single-mode optical field via the $n$-photon exciting process. Here, the two-level system is strongly driven by a near-resonant monochromatic field, and hence the system can work in the Mollow regime, in which a super-Rabi oscillation between the zero-photon state and the $n$-photon state can take place under proper resonant conditions. We calculate the photon number populations and the standard equal-time high-order correlation functions, and find that the multiple-photon bundle emission can occur in this system. The multiple-photon bundle emission is also confirmed by investigating the quantum trajectories of the state populations and both the standard and generalized time-delay second-order correlation functions for multiple-photon bundle. Our work paves the way towards the study of multiple-photon quantum coherent devices, with potential application in quantum information sciences and technologies.
