Distinguishability and Accessible Information in Quantum Theory
TL;DR: This document focuses on translating various information-theoretic measures of distinguishability for probability distributions into measures of distin- guishability for quantum states, and gives a way of expressing the problem so that it appears as algebraic as that of the problem of finding quantum distinguishability measures.

On the relative entropy
TL;DR: For a subset of ℬ(ℋ) (the bounded operators on a Hilbert space) containing the unit, and σ and ρ restrictions of states on the bounded operators, the entropy of σ relative to ρ given the information in A is defined and given an axiomatic characterisation.

Compound Channels, Transition Expectations, and Liftings
Luigi Accardi,Masanori Ohya +1 more
TL;DR: In this paper, the notion of lifting was introduced as a generalization of the compound state introduced in [21] and [22] and it allows a unified approach to the problems of quantum measurement and signal transmission through quantum channels.

Complexities and Their Applications to Characterization of Chaos
TL;DR: In this paper, the concept of complexity in information dynamics is discussed and the chaos degree defined by the complexity is applied to examine chaotic behavior of logistic map in information dynamics.

Quantum-mechanical communication theory
TL;DR: In this paper, the problem of finding the structure and performance of the receiver that yields the best performance in the reception of signals that are described quantum-mechanically is discussed, with the laws of quantum mechanics taken into account.

Quantum information theory
TL;DR: In this paper, a generalization of the classical information theory of Shannon to the quantum case has been proposed, which is based on the generalized quantum mechanics of open systems and the generalized concept of observable (semiobservable) concepts.

Sufficiency, KMS condition and relative entropy in von Neumann algebras.
TL;DR: In this article, the concept of sufficiency is more or less considered through the informativity of a certain subalgebra with respect to a given alge- bra for a dynamical system of interest.
