Autoparallelity of Quantum Statistical Manifolds in Light of Quantum Estimation Theory
Hiroshi Nagaoka, Akio Fujiwara
In this paper we study the autoparallelity w.r.t. the e-connection for an information-geometric structure called the SLD structure, which consists of a Riemannian metric and mutual…
Coherence-variance uncertainty relation and coherence cost for quantum measurement under conservation laws
Hiroyasu Tajima, Hiroshi Nagaoka
Uncertainty relations are one of the fundamental principles in physics. It began as a fundamental limitation in quantum mechanics, and today the word {\it uncertainty relation} is…
Macroscopic Thermodynamic Reversibility in Quantum Many-Body Systems
Philippe Faist, Takahiro Sagawa, Kohtaro Kato +2
The resource theory of thermal operations, an established model for small-scale thermodynamics, provides an extension of equilibrium thermodynamics to nonequilibrium situations. On…
Asymptotic Reversibility of Thermal Operations for Interacting Quantum Spin Systems via Generalized Quantum Stein's Lemma
Takahiro Sagawa, Philippe Faist, Kohtaro Kato +3
For quantum spin systems in any spatial dimension with a local, translation-invariant Hamiltonian, we prove that asymptotic state convertibility from a quantum state to another one…
The Converse Part of The Theorem for Quantum Hoeffding Bound
Hiroshi Nagaoka
We prove the converse part of the theorem for quantum Hoeffding bound on the asymptotics of quantum hypothesis testing, essentially based on an argument developed by Nussbaum and S…
A New Proof of the Channel Coding Theorem via Hypothesis Testing in Quantum Information Theory
Tomohiro Ogawa, Hiroshi Nagaoka
A new proof of the direct part of the quantum channel coding theorem is shown based on a standpoint of quantum hypothesis testing. A packing procedure of mutually noncommutative op…
