    "abstract": "A simple model describing depolarization channels with zero-bandwidth\nenvironment is presented and exactly solved. The environment is modelled by\nLorentzian, telegraphic and Gaussian zero-bandwidth noises. Such channels can\ngo beyond the standard Markov dynamics and therefore can illustrate the\ninfluence of memory effects of the noisy communication channel on the\ntransmitted information. To quantify the disturbance of quantum states the\nentanglement fidelity between arbitrary input and output states is\ninvestigated.",
