We present a scheme for transferring quantum information, which is based on the nonresonant interaction of two two_level atoms with a single_mode cavity field. We show that quantum information can be transferred from one atom to another atom, and from cavity mode to two atoms by manipulating the interactions between cavity field and two atoms, and the information contained in the transferred atom or cavity mode is completely erased.
