Abstract
We propose a scheme for using a spin chain with fixed symmetry interaction as a channel for perfect quantum communication. The perfect quantum communication is determined by the eigenvalues that form a special arithmetical progression, the concrete interaction parameter is obtained as a function of integer and perfect transmission time . There are infinite choices of for perfect transmission and one can design the channel according to the requirement of . This scheme will provide more choices of spin chain for future experiment in quantum communication.
