A Pedagogical Intrinsic Approach to Relative Entropies as Potential Functions of Quantum Metrics: the $q$-$z$ Family

Florio M. Ciaglia, Fabio Di Cosmo, Marco Laudato +4

The so-called $q$-z-\textit{Rényi Relative Entropies} provide a huge two-parameter family of relative entropies which includes almost all well-known examples of quantum relative en…
