Quantum Wire as Open System
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 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.
