Continuity of quantum channel capacities

Speaker: Debbie Leung
Affiliation: University of Waterloo
Room: Mathematics & Computer Building (MC) 5158

Abstract:

Many capacities of a quantum channel are given by expressions that involve asymptotically large number of uses of the channel, thus, there is no a priori reason for the capacities to be continuous. 
In this talk, we prove that the ability to transmitt classical data, private classical data, quantum data with or without free classical communication on the side are all continuous. 

Joint work with Graeme Smith from IBM TJ Watson Research Center.
