Here, we investigate a two-way quantum communication protocol using a spin chain placed in an external magnetic field. In our scheme, Alice and Bob each play the role of a sender and a receiver as two states cos({\\theta}1/2)|0> + sin({\\theta}1/2)exp(i{\\phi}1)|1>, cos({\\theta}2/2)|0> + sin({\\theta}2/2)exp(i{\\phi}2)|1> are transferred through one channel simultaneously.
