Entropic Uncertainty Relations via Direct-Sum Majorization Relation for Generalized Measurements
We derive an entropic uncertainty relation for generalized positive-operator-valued measure (POVM) measurements via a direct-sum majorization relation using Schur concavity of entropic quantities in a finite-dimensional Hilbert space. Our approach provides a significant improvement of the uncertaint...
