How to Quantify a Dynamical Quantum Resource by Gour, Gilad, Winter, Andreas

“…We show that the generalization of the relative entropy of a resource from states to channels is not unique, and there are at least six such generalizations…”

Mutually unbiased measurements in finite dimensions by Kalev, Amir, Gour, Gilad

“…We generalize the concept of mutually unbiased bases (MUB) to measurements which are not necessarily described by rank one projectors. As such, these…”
