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…

The signaling dimension in generalized probabilistic theories
Michele Dall'Arno, Alessandro Tosini, Francesco Buscemi
The signaling dimension of a given physical system quantifies the minimum dimension of a classical system required to reproduce all input/output correlations of the given system. T…
