Denes Petz is well recognized expert of Quantum Mechanics and Quantum
Information.
His popular book coauthored with M. Ohya “Quantum Entropy and its
Use” had its second printing in 2004. At present he has positions
in a mathematical research institute and at the technical university in
Budapest.
His main research area is noncommutative probability and quantum information
theory.

Abstract 


The relative entropy will be introcuded first in classical
information theory and then I move to the quantum setting.
Basic properties of the quantity will be discussed, in particular the
monotonicity and application to the strong subbadditivity of the von Neumann
entropy will be given.
The role of relative entropy in the hypothesis testing and sufficient
coarsegrainings will be treated shortly.
