Retraction Theorems for Group Compactifications

Yair Hartman, Aranka Hrušková, Mehrdad Kalantar +1

We characterize group compactifications of discrete groups for which there exists an equivariant retraction onto the boundary. In particular, we prove an equivariant analogue of Br…

More examples of additivity violation of the regularized minimum output entropy in the commuting-operator setup

Mehrdad Kalantar, Homayoon Shobeiri

We generalize recent results of Collins and Youn (2022), presenting new classes of quantum channels violating the additivity of the regularized minimum output entropy in the commut…
