Abstract

We propose a scheme to realize a special quantum cloning machine (QCM) in cavity quantum electrodynamics (QED). The QCM can copy the information from one atom to another two distant atoms trapped in cavity QED with the help of a single-photon pulse. By choosing different parameters, we can perform an optimal symmetry 12 real state QCM and an optimal symmetry 13 economical real state QCM.
