Abstract

In \cite{Tre_PSI20} we introduce the concept of a μ\mu-norm for a bounded operator in a Hilbert space. The main motivation is the extension of the measure entropy to the case of quantum systems. In this paper we recall the basic results from \cite{Tre_PSI20} and present further results on the μ\mu-norm. More precisely, we specify three classes of unitary operators for which the μ\mu-norm generates a bistochastic operator. We plan to use the latter in the construction of quantum entropy.
