摘要
We propose an experimentally feasible scheme to implement quantum dense coding by the interaction of two three-level Rydberg atoms with nonresonant cavities. The success probability of the scheme is close to 1, and the distance of information transmission is much longer than that of NMR. (C) 2003 Elsevier B.V. All rights reserved.
