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. |
