  In this paper, we first demonstrate how to realize quantum state transferring
(QST) from one atom to another based on quantum Zeno dynamics. Then, the QST
protocol is generalized to realize the quantum state swapping (QSS) between two
arbitrary atoms with the help of a third one. Furthermore, we also consider the
QSS within a quantum network. The influence of decoherence is analyzed by
numerical calculation. The results demonstrate that the protocols are robust
against cavity decay.
