Description:
Author(s): Felix Leditzky, Eneet Kaur, Nilanjana Datta, and Mark M. Wilde We study quantum channels that are close to another channel with weakly additive Holevo information, and we derive upper bounds on their classical capacity. Examples of channels with weakly additive Holevo information are entanglement-breaking channels, unital qubit channels, and Hadamard channels. ... [Phys. Rev. A 97, 012332] Published Thu Jan 25, 2018
