Double Markovity for quantum systems
Masahito Hayashi, Jinpei Zhao
The subadditivity-doubling-rotation (SDR) technique is a powerful route to Gaussian optimality in classical information theory and relies on strict subadditivity and its equality-c…
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…
Universal classical-quantum channel resolvability and private channel coding
Takaya Matsuura, Masahito Hayashi, Min-Hsiu Hsieh
We address the problem of constructing fully universal private channel coding protocols for classical-quantum (c-q) channels. Previous work constructed universal decoding strategie…
Structured quantum learning via em algorithm for Boltzmann machines
Takeshi Kimura, Kohtaro Kato, Masahito Hayashi
Quantum Boltzmann machines (QBMs) are generative models with potential advantages in quantum machine learning, yet their training is fundamentally limited by the barren plateau pro…
Local hypothesis testing between a pure bipartite state and the white noise state
Masaki Owari, Masahito Hayashi
In this paper, we treat a local discrimination problem in the framework of asymmetric hypothesis testing. We choose a known bipartite pure state as an alternative hypothesi…
