摘要：
We present a scheme to implement the three-qubit Fredkin gate. The scheme uses an atomic ensemble consisting of four-level atoms interacting resonantly with a two-mode field. Both the situations with and without cavity decay are considered. We discuss the advantages and the experimental feasibility of our scheme.
