The Saturation of Several Universal Inequalities in Information-Processing
arXiv:1209.5545 · doi:10.1088/0253-6102/63/4/427
Abstract
In this paper, we characterize the saturation of four universal inequalities in quantum information theory, including a variant version of strong subadditivity inequality for von Neumann entropy, the coherent information inequality, the Holevo quantity and average entropy inequalities. These results shed new light on quantum information inequalities.
