Abstract

In this paper, we first define quantum Jensen-Shannon divergence (QJSD) between quantum states in infinite-dimensional case and discuss its properties. Then, using the probabilistic coupling technique, we further propose the notion of quantum Jensen- Shannon divergence (QJSD) between quantum ensembles. Some fundamental properties of this quantity are also discussed.
