Remark on the coherent information saturating its upper bound

Quantum Physics 2012-10-29 v2

Abstract

Coherent information is a useful concept in quantum information theory. It connects with other notions in data processing. In this short remark, we discuss the coherent information saturating its upper bound. A necessary and sufficient condition for this saturation is derived.
