We investigate a system composed of $N$ coupled cavities and two-level atomsinteracting one at a time. Adjusting appropriately the atom-field detuning, andmake the hopping rate of photons between neighboring cavities, $A$, greaterthan the atom-field coupling $g$ (i.e. $A>>g$), we can eliminate theinteraction of the atom with the nonresonant normal modes reducing the dynamicsto the interaction of the atom with only a single-mode. As an application ofthis interaction, we analyze the transmission of an arbitrary atomic quantumstate between distant coupled cavities. In the ideal case, we obtain a flexibleand perfect quantum communication. Considering the influence of dissipation aninteresting parity effect emerge and we obtain $N$ maximum in which it is stillpossible to achieve a quantum communication more efficient than a purelyclassical channel between the ends. We also studied important sources ofimperfections in procedure execution.
