An experimentally feasible scheme for implementing quantum dense coding in cavity QED is proposed. In the scheme a W-class state can first be prepared by letting the atoms interact simultaneously with a highly detuned cavity mode. Then the states coded on this W-class state can be exactly distinguished by detecting atomic states. The scheme is insensitive to the cavity field, and the quantum dense coding can be realized in a simple way.

Quantum mechanics allows one to encode the information in the superposition of a quantum state which embodies the nature of quantum nonlocality. Here we propose a realizable physical scheme for a multiparticle quantum dense coding (QDC) between two users in cavity quantum electrodynamics (QED). We also discuss the feasibility of our scheme within current technology.

Cavity Decay

We propose an experimentally feasible scheme for implementing quantum dense coding in cavity QED. In this scheme, the multi-atoms interact simultaneously with a highly detuned cavity mode, and are driven by a strong classical field. The scheme is insensitive to the cavity decay and the thermal field. Only one interaction between atoms and cavity is required. Multi-atom's GHZ-states can be exactly distinguished via detecting the atomic state, and the quantum dense coding can be realized in a simple way.
