Notes on multiplicativity of maximal output purity for completely positive qubit maps
Koenraad M. R. Audenaert
A problem in quantum information theory that has received considerable attention in recent years is the question of multiplicativity of the so-called maximal output purity (MOP) of…

Subadditivity of q-entropies for q>1
Koenraad M. R. Audenaert
I prove a basic inequality for Schatten q-norms of quantum states on a finite-dimensional bipartite Hilbert space H_1\otimes H_2: 1+||ρ||_q \ge ||\trace_1ρ||_q + ||\trace_2ρ||_q. T…
