Quantum dense coding using a peculiar tripartite entangled state

Following a recent proposal ( Phys. Lett. A 346(2005) 330) about quantum dense coding using a tripartiteentangled GHZ state and W state, this paper proposes anexperimentally feasible scheme for dense coding in cavity QED byusing another peculiar tripartite entangled state. In the schemethe atoms interact simultaneously with a highly detuned cavitymode with the assistance of a classical field, the successfulprobability of dense coding scheme with this peculiar tripartiteentangled state equals 1.
