The operational no-signalling constraints and their implications
Michał Eckstein, Tomasz Miller, Ryszard Horodecki +2
The study of quantum correlations within relativistic spacetimes, and the consequences of relativistic causality on information processing using such correlations, has gained much…

The max-type quasimetrics on probability simplices
Michał Eckstein, Tomasz Miller, Karol Życzkowski
Quasimetric spaces form a natural framework to study distance problems with an inherent directional asymmetry. We introduce a simple novel class of quasimetrics on probability simp…

Distances between pure quantum states induced by a distance matrix
Tomasz Miller, Rafał Bistroń
Given an distance matrix, we construct an infinite family of distances (where ) on the complex projective space modelling th…
