An essential overview of quantum information Information, whether inscribed as a mark on a stone tablet orencoded as a magnetic domain on a hard drive, must be stored in aphysical object and thus made subject to the laws of physics.Traditionally, information processing such as computation occurredin a framework governed by laws of classical physics. However,information can also be stored and processed using the states ofmatter described by non-classical quantum theory. Understandingthis quantum information, a fundamentally different type ofinformation, has been a major project of physicists and informationtheorists in recent years, and recent experimental research hasstarted to yield promising results. Quantum Approach to Informatics fills the need for a conciseintroduction to this burgeoning new field, offering an intuitiveapproach for readers in both the physics and information sciencecommunities, as well as in related fields. Only a basic backgroundin quantum theory is required, and the text keeps the focus onbringing this theory to bear on contemporary informatics. Insteadof proofs and other highly formal structures, detailed examplespresent the material, making this a uniquely accessibleintroduction to quantum informatics. Topics covered include: * An introduction to quantum information and the qubit * Concepts and methods of quantum theory important forinformatics * The application of information concepts to quantum physics * Quantum information processing and computing * Quantum gates * Error correction using quantum-based methods * Physical realizations of quantum computing circuits A helpful and economical resource for understanding this excitingnew application of quantum theory to informatics, Quantum Approachto Informatics provides students and researchers in physics andinformation science, as well as other interested readers with somescientific background, with an essential overview of the field.

Quantum Computation and Quantum Information (QIP) deals with the identification and use of quantum resources for information processing. This includes three main branches of investigation: quantum algorithm design, quantum simulation and quantum communication, including quantum cryptography. Along the past few years, QIP has become one of the most active area of research in both, theoretical and experimental physics, attracting students and researchers fascinated, not only by the potential practical applications of quantum computers, but also by the possibility of studying fundamental physics at the deepest level of quantum phenomena. NMR Quantum Computation and Quantum Information Processing describes the fundamentals of NMR QIP, and the main developments which can lead to a large-scale quantum processor. The text starts with a general chapter on the interesting topic of the physics of computation. The very first ideas which sparkled the development of QIP came from basic considerations of the physical processes underlying computational actions. In Chapter 2 it is made an introduction to NMR, including the hardware and other experimental aspects of the technique. In Chapter 3 we revise the fundamentals of Quantum Computation and Quantum Information. The chapter is very much based on the extraordinary book of Michael A. Nielsen and Isaac L. Chuang, with an upgrade containing some of the latest developments, such as QIP in phase space, and telecloning. Chapter 4 describes how NMR generates quantum logic gates from radiofrequency pulses, upon which quantum protocols are built. It also describes the important technique of Quantum State Tomography for both, quadrupole and spin 1/2 nuclei. Chapter 5 describes some of the main experiments of quantum algorithm implementation by NMR, quantum simulation and QIP in phase space. The important issue of entanglement in NMR QIP experiments is discussed in Chapter 6. This has been a particularly exciting topic in the literature. The chapter contains a discussion on the theoretical aspects of NMR entanglement, as well as some of the main experiments where this phenomenon is reported. Finally, Chapter 7 is an attempt to address the future of NMR QIP, based in very recent developments in nanofabrication and single-spin detection experiments. Each chapter is followed by a number of problems and solutions. * Presents a large number of problems with solutions, ideal for students * Brings together topics in different areas: NMR, nanotechnology, quantum computation * Extensive references

This book provides the reader with the mathematical framework required to fully explore the potential of small quantum information processing devices. As decoherence will continue to limit their size, it is essential to master the conceptual tools which make such investigations possible. A strong emphasis is given to information measures that are essential for the study of devices of finite size, including Rényi entropies and smooth entropies. The presentation is self-contained and includes rigorous and concise proofs of the most important properties of these measures. The first chapters will introduce the formalism of quantum mechanics, with particular emphasis on norms and metrics for quantum states. This is necessary to explore quantum generalizations of Rényi divergence and conditional entropy, information measures that lie at the core of information theory. The smooth entropy framework is discussed next and provides a natural means to lift many arguments from information theory to the quantum setting. Finally selected applications of the theory to statistics and cryptography are discussed. The book is aimed at graduate students in Physics and Information Theory. Mathematical fluency is necessary, but no prior knowledge of quantum theory is required.

It has been recognised recently that the strange features of the quantum world could be used for new information transmission or processing functions such as quantum cryptography or, more ambitiously, quantum computing. These fascinating perspectives renewed the interest in fundamental quantum properties and lead to important theoretical advances, such as quantum algorithms and quantum error correction codes. On the experimental side, remarkable advances have been achieved in quantum optics, solid state physics or nuclear magnetic resonance. This book presents the lecture notes of the Les Houches Summer School on ‘Quantum entanglement and information processing’. Following the long tradition of the les Houches schools, it provides a comprehensive and pedagogical approach of the whole field, written by renowned specialists. One major goal of this book is to establish connections between the communities of quantum optics and of quantum electronic devices working in the area of quantum computing. When two communities share the same goals, the universality of physics unavoidably leads to similar developments. However, the communication barrier is often high, and few physicists are able to overcome it. This school has contributed to bridge the existing gap between communities, for the benefit of the future actors in the field of quantum computing. The book thus combines introductory chapters, providing the reader with a sufficiently wide theoretical framework in quantum information, quantum optics and quantum circuits physics, with more specialized presentations of recent theoretical and experimental advances in the field. This structure makes the book accessible to any graduate student having a good knowledge of basic quantum mechanics, and extremely useful to researchers. · Covers quantum optics, solid state physics and NMR implementations · Pedagogical approach combining introductory lectures and advanced chapters · Written by leading experts in the field · Accessible to all graduate students with a basic knowledge of quantum mechanics

This book is a simple introduction to Quantum Information Processing (QIP) for non-experts. It is accessible to undergraduates, postgraduates, and scientists from "non-physics" disciplines such as engineering, computer science, and chemistry with interest in learning about QIP. The book uses simple examples (instead of technical details) to bring out the key features of QIP, which makes the book a useful resource for instructors as well. Introduction to Quantum Information Processing begins with a discussion of the very basic ideas of QIP and the underpinning quantum theory needed to understand them. The fundamental aspects of quantum theory, which play center stage in QIP, are presented and illustrated with simple examples. The book continues with a presentation of the various applications and algorithms of QIP, and finishes with a discussion on the future of a possible quantum information technology industry. There are no competing introductory texts for Quantum Information Processing on the market. *Authors are world renowned and part of a leading industry research team at Hewlett Packard. *An excellent course text for undergraduate students in physics or related scientific disciplines. *An excellent introduction for scientists and engineers outside of QIP but with interest in learning about the field.
