Abstract

We show that any bijective map on the space of all quantum states which preserves the Jensen–Shannon divergence is induced by a unitary or antiunitary operator.

Maps on states preserving the relative entropy

Lajos Molnár

Let H be a finite dimensional Hilbert space. The aim of this short note is to prove that every bijective map on the space S(H) of all density operators on H which preserves the relative entropy is of the form ϕ(ρ)=UρU* with some unitary or antiunitary operator U on H.

Maps on quantum states preserving Bregman and Jensen divergences

Dániel Virosztek

We describe the structure of the bijective transformations on the set of density operators which preserve the Bregman f-divergence for an arbitrary differentiable strictly convex function f. Furthermore, we determine the preservers of the Jensen f-divergence in the case when the generating function f belongs to a recently introduced function class called Matrix Entropy Class.
