Let S (ρ) be the von Neumann entropy of a density matrix ρ. Weak monotonicity asserts that S (ρ AB)-S (ρ A)+ S (ρ BC)-S (ρ C)≥ 0 for any tripartite density matrix ρ ABC, a fact that is …

In this paper we investigate the inequality $ S_q (\rho_ {123})+ S_q (\rho_2)\leq S_q (\rho_ {12})+ S_q (\rho_ {23})\,(*) $ where $\rho_ {123} $ is a state on a finite dimensional Hilbert …

Recently, there has been focus on determining the conditions under which the data processing inequality for quantum relative entropy is satisfied with approximate equality. The …
In this paper, that is a continuation of recent work [SS Dragomir, Some inequalities for relative operator entropy, Preprint RGMIA Res. Rep. Coll. 18 (2015), Art. 145. http://rgmia …

A simpler approach to the characterization of vanishing conditional mutual information is presented. Some remarks are given as well. More specifically, relating the conditional …

We describe recent work of Kim [J. Math. Phys. 53, 122204 (2012)] to show that operator convex functions associated with quasi-entropies can be used to prove a large class of new …
In this thesis, I will discuss how information-theoretic arguments can be used to produce sharp bounds in the studies of quantum many-body systems. The main advantage of this …
