Operator algebra approach to quantum capacities

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Using a suitable algebraic setup, we find new estimates of the quantum capacity and the potential quantum capacity for non-degradable channels obtained by random unitaries associated with a finite group. This approach can be generalized to quantum groups and uses new tools from operator algebras and interpolation of Rényi-type entropies. As an application, we obtain new estimates for the depolarizing channel in high dimension.
