Quantum -divergences via Nussbaum-Szkoła Distributions in Semifinite von Neumann Algebras
Theodoros Anastasiadis, George Androulakis
In this article, we prove that the quantum -divergence between two normal states on a semifinite von~Neumann algebra is equal to the classical -divergence between two corresp…

Optimal lower bound for lossless quantum block encoding
George Androulakis, Rabins Wosti
Consider a general quantum stochastic source that emits at discrete time steps quantum pure states which are chosen from a finite alphabet according to some probability distributio…

Classes of strictly singular operators and their products
George Androulakis, Pandelis Dodos, Gleb Sirotkin +1
V. D. Milman proved in \cite{Milman:70} that the product of two strictly singular operators on () or on is compact. In this note we utilize Schre…
