中文摘要：

运用∧型三能级原子与相干态光场大失谐作用，在腔量子电动力学体系中制备原子与相干态光场的最大纠缠态，并以此作为量子通道在经典场辅助作用下远程制备可随意操控的相干态光场任意叠加态。经过计算，得出对于叠加系数为实数的相干态光场的叠加态，通过适当旋转操作，远程制备成功的概率是100％。最后讨论了实验上实现此方案的可行性和所具备的应用优势。

英文摘要：

Using the highly detuned interaction between three-level ∧-type atom and coherent optical field, we can get the maximally entangled state between the atom and the coherent optical field. With the help of a Ramsey zone and this prepared quantum channel an arbitrary superposition of a pair of coherent states can be remotely prepared freely in cavity QED. The possibility for a successful preparation is 100% when the superposition coefficients are real. The experimental so discussed. feasibility and the advantage of applications are al-
