摘要:

提出了一种基于高Q光腔中的原子与一行波光场相互作用来制备光场激发相干态和二阶激发相干态的新方法。与已提出的方法比较,该方法具备一些优点:不应用微扰理论且除了最后测量外仅用一步就可完成制备,但该方法成功几率只有50%。

Abstract:

A new method was proposed to prepare excited coherent states and two-order excited coherent states, which is based on the interaction of atom inside high-Q cavity with a traveling wave light field. Compared with other presented methods, this method has some merits such as the perturbation theory is not used and one step preparation is only taken except for the final measurement. However, the success probability for this method is only 50%.

Key words: quantum optics, excited coherent states, high-Q cavity, traveling wave light field
