Monoparametric family of metrics derived from classical Jensen–Shannon divergence
(Elsevier Science, 2018-04-01)
Jensen–Shannon divergence is a well known multi-purpose measure of dissimilarity between probability distributions. It has been proven that the square root of this quantity is a true metric in the sense that, in addition ...
Purification-based metric to measure the distance between quantum states and processes
(American Physical Society, 2013-06)
In this work we study the properties of a purification-based entropic metric for measuring the distance between both quantum states and quantum processes. This metric is defined as the square root of the entropy of the ...
