论文摘要
我们展示了如何通过对参数放大器腔内量子量的哈密顿量的同构来实现腔量量子电动力学的 - 拉比模型。这种实现可以通过应用于包含值和阈值以下的参数振荡器的参数放大器腔的探针来观察RABI模型的全光谱。同构的一个重要结果是，实际频率被引人入胜的替代，这使得达到超强耦合方案是可行的。我们发现，在该策略中，探测的光谱显示出狭窄的谐振峰，该峰追溯到地面和第一激发状态之间的过渡。这些状态的确切形式是在能量交叉处给出的，然后在数值上扩展。在十字路口，本征态是纠缠的野外状态和原子，在挤压猫状态下发现了田间。
We show how the Jaynes--Cummings--Rabi model of cavity quantum electrodynamics can be realized via an isomorphism to the Hamiltonian of a qubit inside a parametric amplifier cavity. This realization clears the way to observe the full spectrum of the Rabi model via a probe applied to a parametric amplifier cavity containing a qubit and a parametric oscillator operating below threshold. An important outcome of the isomorphism is that the actual frequencies are replaced by detunings which make it feasible to reach the ultra-strong coupling regime. We find that inside this regime the probed spectrum displays a narrow resonance peak that is traced back to the transition between ground and first excited states. The exact form of these states is given at an energy crossing and then extended numerically. At the crossing, the eigenstates are entangled states of field and atom where the field is found inside squeezed cat states.
