Abstract: Study of super operators, norms on super operators (referred to as super operator norms) and the minimum output -Re'nyi entropy of a typical quantum channel. These are used to study the additivity conjecture and the argument used by Hayden–Winter disproving the additivity conjecture for the minimal output p-Re'nyi entropy (for > 1).
