Remote Preparation of an Arbitrary Superposition of Coherent States in Cavity QED
Yang Ming · Journal of Hefei Teachers College · 2009
Using the highly detuned interaction between three-level Λ-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 feasibility and the advantage of applications are also discussed.
