M. Bhattacharya, K. D. Osborn, Ari Mizel

摘要:

我们进行了量子力学分析超导谐振器的介电损耗所产生的带电二能级系统。我们提出的数值和分析描述的能量衰减的动态谐振器内的Jaynes-Cummings模型。我们的分析使我们能够区分模型的强耦合和弱耦合制度,并描述在每个制度的情况下,两级系统是不饱和或饱和。我们发现,在弱耦合情况下,量子理论与经典模型一致。然而,对于强耦合的量子理论预测的损失低于经典理论在不饱和制度。另外,与经典理论相反,在强耦合量子理论中出现饱和的光子数与谐振腔和二能级系统之间的耦合无关。

英文摘要:

We perform a quantum mechanical analysis of superconducting resonators subject to dielectric loss arising from charged two-level systems. We present numerical and analytical descriptions of the dynamics of energy decay from the resonator within the Jaynes-Cummings model. Our analysis allows us to distinguish the strong and weak coupling regimes of the model and to describe within each regime cases where the two-level system is unsaturated or saturated. We find that the quantum theory agrees with the classical model for weak coupling. However, for strong coupling the quantum theory predicts lower loss than the classical theory in the unsaturated regime. Also, in contrast to the classical theory, the photon number at which saturation occurs in the strong coupling quantum theory is independent of the coupling between the resonator and the two-level system.
