  Quantum dense coding is a protocol for transmitting two classical bits of
information from a sender (Alice) to a remote receiver (Bob) by sending only
one quantum bit (qubit). In this article, we propose an experimentally feasible
scheme to realize quantum dense coding \textit{via} entanglement swapping in a
cavity array containing a certain number of two-level atoms. Proper choice of
system parameters such as atom-cavity couplings and inter-cavity couplings
allows perfect transfer of information. A high fidelity transfer of information
is shown to be possible by using recently achieved experimental values in the
context of photonic crystal cavities and superconducting resonators. To mimic
experimental imperfections, disorder in both the coupling strengths and
resonance frequencies is considered.
