Abstract  

The Bregman operator divergence is introduced for density matrices by differentiation of the matrix-valued function xx log x. This quantity is compared with the relative operator entropy of Fujii and Kamei. It turns out that the trace is the usual Umegaki’s relative entropy which is the only intersection of the classes of quasi-entropies and Bregman divergences.
