Information causality beyond the random access code model
Baichu Yu, Valerio Scarani
The paper introduces a new quantifier for information causality based on redundant information, which closes several gaps between the principle and the quantum set of correlations,…

Extension of the Alberti-Uhlmann criterion beyond qubit dichotomies
Michele Dall'Arno, Francesco Buscemi, Valerio Scarani
The Alberti-Uhlmann criterion states that any given qubit dichotomy can be transformed into any other given qubit dichotomy by a quantum channel if and only if the testing region o…

Observational entropy with general quantum priors
Ge Bai, Dominik Šafránek, Joseph Schindler +2
Observational entropy captures both the intrinsic uncertainty of a thermodynamic state and the lack of knowledge due to coarse-graining. We demonstrate two interpretations of obser…
