Entropic Uncertainty Relations via Direct-Sum Majorization Relation for Generalized Measurements
Kyunghyun Baek, Hyunchul Nha, Wonmin Son
We derive an entropic uncertainty relation for generalized positive-operator-valued measure (POVM) measurements via a direct-sum majorization relation using Schur concavity of entr…

Necessary and sufficient condition for joint measurability
Jeongwoo Jae, Kyunghyun Baek, Junghee Ryu +1
In order to analyze joint measurability of given measurements, we introduce a Hermitian operator-valued measure, called -measure, such that it has marginals of positive operator…
