TLDR
A short review of the development of the physical information theory is presented and BrillouinS conjecture of minimum enerrgy per unit of information is proved for this type of channels.Abstract:
A short review of the development of the physical information theory is presented. The entropy defect principle is formulated for quasiclassical systems. The concept of ideal physical information channels is iintroduced. It is shown that information properties of such a channel with independent additive noise can be ontained from the thermodynamic description of the physical system that transmits information. BrillouinS conjecture of minimum enerrgy per unit of information is proved for this type of channels.read more

Zig-zag path to understanding
TL;DR: The fundamental physical limits of information handling have developed along a very convoluted path as discussed by the authors, and most of the initially plausible physical conjectures have turned out to be wrong, and a participant's personal view of these events is not a disciplined contribution to the history of science.

Physical Information Theory Part II: Quantum Systems
TL;DR: In this paper, the concept of information (by Shannon) is generalized for quantum statistical ensembles, and the consistent quantum-theoretical form of the entropy defect principle is obtained.

What information to measure? How to measure it?
TL;DR: This paper offers a concise report of the researches driven on the problem of the information definition and defines the concept of signifier using the mathematical language, and discusses some features of this mathematical definition.

The creativity of authors in defining the concept of information
Paolo Rocchi,Andrea Resca +1 more
TL;DR: The authors found that researchers take account of a wide variety of perspectives yet overlook the notion of information as used by computing practitioners such as electronic engineers and software developers.

Information Theory and Statistical Mechanics. II
TL;DR: In this article, the authors consider statistical mechanics as a form of statistical inference rather than as a physical theory, and show that the usual computational rules, starting with the determination of the partition function, are an immediate consequence of the maximum-entropy principle.

Quantum detection and estimation theory
TL;DR: In this article, the optimum procedure for choosing between two hypotheses, and an approximate procedure valid at small signal-to-noise ratios and called threshold detection, are presented, and a quantum counterpart of the Cramer-Rao inequality of conventional statistics sets a lower bound to the mean-square errors of such estimates.

Quantum cryptography without Bell's theorem.
TL;DR: A related but simpler EPR scheme is described and it is proved it secure against more general attacks, including substitution of a fake EPR source and the original 1984 key distribution scheme of Bennett and Brassard, which uses single particles instead of EPR pairs.
