The paper's central theorem, that energy-constrained quantum channels maximize channel entropy if and only if they are absolutely thermalizing, is false: other channels can also reach the maximum.

abstract
The aim of these lectures is to investigate the transfer of information occurring in course of quantum interactions. In particular, I shall explore circumstances in which such an information transfer with the quantum environment of the considered quantum system leads to the destruction of the phase coherence between the states of the privileged basis in the system Hilbert space. This basis shall be called the pointer basis. I shall argue that states of this pointer basis correspond to the ``classical'' states of the observables of the quantum system in question.

Maximum entropy principle for quantum processes
The paper's central theorem, that energy-constrained quantum channels maximize channel entropy if and only if they are absolutely thermalizing, is false: other channels can also reach the maximum.
