A Domain of Unital Channels

Johnny Feng, Naval Research Laboratory, Tulane University
Quantum Physics and Logic 2010, May 2010, University of Oxford

The common practice of slightly rewording the first paragraph or two of the introduction and calling it an abstract has always seemed a colossal waste of space to the author. Here, we will try to be as brief and to the point as possible. In this paper we prove the space of unital qubit channels is a Scott domain. We also provide a simple protocol to achieve Holevo capacity for these channels.
