New constructive counterexamples to additivity of minimum output Rényi p-entropy of quantum channels

Szczygielski, Krzysztof; Studziński, Michał (2024-08-28)

In this paper, we present new families of quantum channels for which corresponding minimum output Rényi p-entropy is not additive. Our manuscript is motivated by the results of Grudka et al., J. Phys. A: Math. Theor. 43 ...
