Abstract

We show that the sum uncertainty relations for Wigner–Yanase skew information introduced in Chen et al. (Quantum Inf Process 15:2639–2648, 2016) can hold for an arbitrary metric adjusted skew information. A refinement of one main result in that paper is formulated via a series of lower bounds consisting of the skew information of any prescribed size of the combinations. We also study the metric-adjusted skew information-based uncertainty relations for quantum channels in the spirit of Fu et al. (Quantum Inf Process 18:258, 2019).
