Scheme for implementing quantum dense coding in cavity QED
Ye Liu, Guang‐Can Guo · Physical Review A · 2005
An experimentally feasible scheme for implementing quantum dense coding in cavity QED is proposed. In the scheme the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a classical field. The scheme is insensitive to the cavity decay and the thermal field. Bell states can be exactly distinguished via detecting the atomic state, and the quantum dense coding can be realized in a simple way.
