A Posteriori Certification Framework for Generalized Quantum Arimoto-Blahut Algorithms
Geng Liu, Masahito Hayashi
The generalized quantum Arimoto--Blahut (QAB) algorithm is a powerful derivative-free iterative method in quantum information theory. A key obstacle to its broader use is that exis…

Generalized quantum Arimoto-Blahut algorithm and its application to quantum information bottleneck
Masahito Hayashi, Geng Liu
We generalize the quantum Arimoto-Blahut algorithm by Ramakrishnan et al. (IEEE Trans. IT, 67, 946 (2021)) to a function defined over a set of density matrices with linear constrai…
