We define the entropic bounds, i.e. minimal uncertainty for pairs of unitary testers in distinguishing between unitary transforma- tions not unlike the well known entropic bounds for observables. We show that in the case of specific sets of testers which pairwise saturate the trivial zero bound, the...
