薛定谔猫态的产生与探测及其对Jaynes-Cummings模型的影响

利用大失谐情况下的简并喇曼过程和双光子Jaynes-Cummings模型来产生电磁场中的宏观量子叠加态,即薛定旋风谔猫态,并探讨如何用零频检测的方法来探测这些态。研究了当电磁场初态为薛定谔猫态时,对强度耦合的Jaynes-Cummings模型中原子反转的崩塌与再生现象的影响,将在以相干态为初态所产生的原子反转的崩塌区产生不同程度的再生现象。 关键词：

PRODUCTION AND DETECTION OF SCHRDINGER CAT STATE AND ITS EFFECT ON THE EVOLUTION OF JAYNES-CUMMINGS MODEL

In this article, we have studied how to generate macroscopic quantum superposition states in electromagnetic field, the Schrodinger cat states, from the large-detuning degenerate Raman process and the large-detuning two-photon Jaynes-Cummings model. The homodyne detection of these states is also discussed. When the initial state of the field is the Schrodinger cat state, the effects of the cat state on the collapse and revival phenomena in the intensity-dependent Jaynes-Cummings model are investigated. The revival in varying degrees occurs in the collapse region resulted from the evolution of initial coherent state.
