论文摘要
我们提出了一种通过时间依赖性扰动理论来与Dicke-Stark模型创建选择性相互作用的方法。通过选择正确的旋转框架，我们发现振荡术语的时间取决于原子激发的数量和光子激发的数量。因此，可以通过正确选择两级系统的频率来实现选择性状态之间的Rabi振荡。第二阶选择性相互作用也可以使用此方法研究。然后，可以通过这种选择性相互作用来创建各种状态，例如迪克国家，迪克状态和GHz状态的叠加。数值结果表明，可以通过选择正确的两级系统的适当频率并控制进化时间来创建高富达迪克状态和Greenberger-Horne-Zeilinger状态。
We propose a method to create selective interactions with Dicke-Stark model by means of time-dependent perturbation theory. By choosing the proper rotating framework, we find that the time oscillating terms depend on the number of atomic excitations and the number of photonic excitations. Consequently, the Rabi oscillation between selective states can be realized by properly choosing the frequency of the two-level system. The second order selective interactions can also be studied with this method. Then various states such as Dicke states, superposition of Dicke states and GHZ states can be created by means of such selective interactions. The numerical results show that high fidelity Dicke states and Greenberger-Horne-Zeilinger states can be created by choosing the proper frequency of two-level system and controlling the evolution time.
