Abstract
The faithful exchange of quantum information will soon become one of the challenges of the emerging quantum information technology. One of the possible solutions is to transfer a superposition through a chain of properly coupled spins. Such a system is called a quantum wire. We discuss the transfer in a quantum wire \cite{christ,niko1,niko2}, when the process of thermalization of the state takes place together with the free evolution. We investigate which encoding scheme is more faithful in certain thermal conditions.
