New constructive counterexamples to additivity of minimum output Rényi p-entropy of quantum channels
Krzysztof Szczygielski, Michał Studziński
In this paper, we present new families of quantum channels for which corresponding minimum output Rényi -entropy is not additive. Our manuscript is motivated by the results of G…

Enhancing phase-covariant channel performance with non-unitality
Katarzyna Siudzińska, Michał Studziński
We analyze quantum communication properties of phase-covariant channels depending on their degree of non-unitality. In particular, we derive analytical formulas for minimal and max…

Two instances of random access code in the quantum regime
Nitica Sakharwade, Michał Studziński, Michał Eckstein +1
We consider two classes of quantum generalisations of Random Access Code (RAC) and study lower bounds for probabilities of success for such tasks. It provides a useful framework fo…
