On n-partite superactivation of quantum channel capacities

Abstract

A generalization of the superactivation of quantum channel capacities to the case of n>2 channels is considered. An explicit example of such superactivation for the 1-shot quantum zero-error capacity is constructed for n=3. Some implications of this example and its reformulation on terms of quantum measurements are described.
