dc.description.abstract
The quantum relative entropy is frequently used as a distance measure between
two quantum states, and inequalities relating it to other distance measures
are important mathematical tools in many areas of quantum informationtheory.
We have derived many such inequalities in previous work. The present paper is
a follow-up on this, and provides a sharp upper bound on the relative entropy
in terms of the trace norm distance and of the smallest eigenvalues of both
states concerned. The result obtained here is more general than the
corresponding one from our previous work. As a corollary, we obtain a sharp
upper bound on the regularised relative entropy introduced by Lendi,
Farhadmotamed, and van Wonderen.
