On the Concavity of Auxiliary Function in Classical-Quantum Channels

Hao-Chung Cheng, Min-Hsiu Hsieh

The auxiliary function of a classical channel appears in two fundamental quantities that upper and lower bound the error probability, respectively. A crucial property of the auxili…

Characterisations of Matrix and Operator-Valued $Φ$ -Entropies, and Operator Efron-Stein Inequalities

Hao-Chung Cheng, Min-Hsiu Hsieh

We derive new characterisations of the matrix $Φ$ -entropy functionals introduced in [Electron.~J.~Probab., 19(20): 1--30, 2014]. Notably, all known equivalent characterisati…
