dc.description.abstract A chain of interacting spin behaves like a quantum mediator (quantum link), which allows two distant parties that control the ends of the chain to exchange quantum messages. We show that over repeated uses without resetting the study of a quantum link can be connected to correlated quantum channels with a finite dimensional environment (finite memory quantum channel). Then, using coding arguments for such kinds of channels and results on mixing channels we present a protocol that allows us to achieve perfect information transmission through a quantum link. en
