Quantum Uncertainty Based on Metric Adjusted Skew Information
Liang Cai
Prompted by the open questions in Gibilisco [Int. J. Software Informatics, 8(3-4): 265, 2014], in which he introduced a family of measurement-induced quantum uncertainty measures v…

Metric adjusted skew information: Convexity and restricted forms of superadditivity
Liang Cai, Frank Hansen
We give a truly elementary proof of the convexity of metric adjusted skew information following an idea of Effros. We extend earlier results of weak forms of superadditivity to gen…

Inequalities for quantum skew information
Koenraad Audenaert, Liang Cai, Frank Hansen
We study quantum information inequalities and show that the basic inequality between the quantum variance and the metric adjusted skew information generates all the multi-operator…
