多光子束态对于诸如量子计量学、量子光刻、量子通信和量子生物学的广泛应用是至关重要的。在这里，我们提出了一个方案，产生多光子束通过虚拟激发量子拉比模型。我们的方法利用了一个三能级原子，其中上两个能级耦合到一个腔场，形成一个具有超强耦合的量子拉比模型，下两个能级之间的跃迁是由两个序列的高斯脉冲驱动。我们表明，通过受激拉曼绝热通道技术，驱动脉冲从量子拉比模型的本征态诱导确定性多光子发射，从而可以在腔输出场中按需产生多光子束。我们计算了输出光子的广义二阶相关函数，结果表明出射光子形成了反聚束多光子束。
Multi-photon bundle states are crucial for a broad range of applications such as quantum metrology, quantum lithography, quantum communication, and quantum biology. Here we propose a scheme that generates multi-photon bundles via virtual excitations in a quantum Rabi model. Our approach utilizes a Ξ-type three-level atom, where the upper two levels are coupled to a cavity field to form a quantum Rabi model with ultrastrong coupling, and the transition between the lower two levels is driven by two sequences of Gaussian pulses. We show that the driving pulses induce deterministic emission of multiple photons from the eigenstates of the quantum Rabi model via the stimulated Raman adiabatic passage technique, and hence can create bundles of multiple photons on-demand in the cavity output field. We calculate the generalized second-order correlation functions of the output photons, which reveal that the emitted photons form antibunched multi-photon bundles.
