Quantum Information Theory Details

Developing many of the major, exciting, pre- and post-millennium developments from the ground up, this book is an ideal entry point for graduate students into quantum information theory. Significant attention is given to quantum mechanics for quantum information theory, and careful studies of the important protocols of teleportation, superdense coding, and entanglement distribution are presented. In this new edition, readers can expect to find over 100 pages of new material, including detailed discussions of Bell's theorem, the CHSH game, Tsirelson's theorem, the axiomatic approach to quantum channels, the definition of the diamond norm and its interpretation, and a proof of the Choi–Kraus theorem. Discussion of the importance of the quantum dynamic capacity formula has been completely revised, and many new exercises and references have been added. This new edition will be welcomed by the upcoming generation of quantum information theorists and the already established community of classical information theorists.

What is Quantum Information?

Category: Livres anglais et trangers,Science,Physics

What is Quantum Information? Details

Combining physics and philosophy, this is a uniquely interdisciplinary examination of quantum information science which provides an up-to-date examination of developments in this field. The authors provide coherent definitions and theories of information, taking clearly defined approaches to considering information in connection with quantum mechanics, probability, and correlations. Concepts addressed include entanglement of quantum states, the relation of quantum correlations to quantum information, and the meaning of the informational approach for the foundations of quantum mechanics. Furthermore, the mathematical concept of information in the communicational context, and the notion of pragmatic information are considered. Suitable as both a discussion of the conceptual and philosophical problems of this field and a comprehensive stand-alone introduction, this book will benefit both experienced and new researchers in quantum information and the philosophy of physics.

The Political Economy of the Eurozone

Category: Livres anglais et trangers,Business & Investing,Economics

The Political Economy of the Eurozone Details

The Eurozone is not a mere currency area. It is also a unique polity whose actors span multiple levels (supranational, national, regional, sectoral) and pursue overlapping economic and political objectives. Current thinking on the Eurozone relies on received categories that struggle to capture these constitutive features. This book addresses this analytical deficit by proposing a new approach to the political economy of the Eurozone, which captures economic and political interdependencies across different levels of decision making and sheds light on largely unexplored problems. The book explores the opportunities afforded by the structure of the Eurozone, and lays the foundations of a political economy that poses new questions and requires new answers. It provides categories that are firmly grounded in the existing configuration of the Eurozone, but are a precondition for overcoming the status quo in analysis and policy.

Security and Game Theory: Algorithms, Deployed Systems, Lessons Learned

Category: Livres anglais et trangers,Computers & Internet,Security & Encryption

Security and Game Theory: Algorithms, Deployed Systems, Lessons Learned Details

Global threats of terrorism, drug-smuggling and other crimes have led to a significant increase in research on game theory for security. Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. A typical approach is to randomize security schedules to avoid predictability, with the randomization using artificial intelligence techniques to take into account the importance of different targets and potential adversary reactions. This book distills the forefront of this research to provide the first and only study of long-term deployed applications of game theory for security for key organizations such as the Los Angeles International Airport police and the US Federal Air Marshals Service. The author and his research group draw from their extensive experience working with security officials to intelligently allocate limited security resources to protect targets, outlining the applications of these algorithms in research and the real world.

Metaphor Wars: Conceptual Metaphors in Human Life

Category: Livres anglais et trangers,Science,Behavioral Sciences

Metaphor Wars: Conceptual Metaphors in Human Life Details

The study of metaphor is now firmly established as a central topic within cognitive science and the humanities. We marvel at the creative dexterity of gifted speakers and writers for their special talents in both thinking about certain ideas in new ways, and communicating these thoughts in vivid, poetic forms. Yet metaphors may not only be special communicative devices, but a fundamental part of everyday cognition in the form of 'conceptual metaphors'. An enormous body of empirical evidence from cognitive linguistics and related disciplines has emerged detailing how conceptual metaphors underlie significant aspects of language, thought, cultural and expressive action. Despite its influence and popularity, there have been major criticisms of conceptual metaphor. This book offers an evaluation of the arguments and empirical evidence for and against conceptual metaphors, much of which scholars on both sides of the wars fail to properly acknowledge.
