Rényi divergence inequalities via interpolation, with applications to generalised entropic uncertainty relations
Alexander McKinlay
We investigate quantum Rényi entropic quantities, specifically those derived from 'sandwiched' divergence. This divergence is one of several proposed Rényi generalisations of the q…

Decomposition Rules for Quantum Rényi Mutual Information with an Application to Information Exclusion Relations
Alexander McKinlay, Marco Tomamichel
We prove decomposition rules for quantum Rényi mutual information, generalising the relation to inequalities between Rényi mutual information and Rényi ent…
