摘要：

We implement a two-atom root swap gate via cavity QED. During the preparation, a cavity-assisted collision between atoms is required, and this does not need any auxiliary atom. The cavity is only virtually excited, thus our scheme is insensitive to the cavity field states and to the cavity decay. The scheme can be implemented by the present cavity QED techniques.
