Die NSA entwickelt einen, Google und die NASA haben sich eine erste kommerzielle Version davon gekauft. Aber was ist das eigentlich, ein Quantencomputer? Das Buch erklärt verständlich und unterhaltsam die magisch anmutenden Phänomene der Quantenphysik und wie sie für unbegreiflich schnell rechnende Computer genutzt werden können. Es zeigt, wie der Quantencomputer und seine Verwandten - gemeint sind neue Technologien, die auf der Quantenphysik basieren - den Alltag ähnlich umwälzen könnten wie einst die Dampfmaschine oder die Entdeckung der Elektronik. Werden Quantencomputer die gängigen Verschlüsselungsverfahren aushebeln? Werden sie eine blitzschnelle Entwicklung neuer Arzneien ermöglichen? Wird es einmal ein Quanteninternet geben und wenn ja, was bringt es? Werden es hyperempfindliche Quantensensoren erlauben, die Gedanken eines Menschen zu lesen? Neben konkreten Beispielen schon existierender Quantentechnologie (etwa Flash-Speicher oder Verschlüsselungsverfahren) gibt Wissenschaftsjournalist Christian Meier einen Überblick über die wichtigsten Laborentwicklungen und zeigt auf, wohin sie führen könnten. Schließlich erfahren Sie, warum manche Physiker glauben, das Universum sei ein einziger Quantencomputer.

Was wir online lesen und sehen, auf Webseiten, in Blogs und sozialen Netzwerken, das ist immer öfter verfremdet und manipuliert. Gefälschte Inhalte werden genutzt, um versteckte Werbung zu platzieren und Einnahmen zu generieren, aber auch um die öffentliche Meinung zu Gunsten von Interessensverbänden und der Politik zu steuern. Über gezielte Desinformation, versteckte Propaganda, gekaufte Google-Platzierungen und vieles mehr wird der Nutzer zum Spielball auf diesem Milliardenmarkt. Und selbst die großen Onlinemedien mischen mit. Neue Technologien der digitalen Welt befeuern den Trend zu rein künstlich generiertem Content. Wir sind an einem Punkt angelangt, an dem wir uns entscheiden müssen: Zwischen einem "freien" oder einem von kommerziellen Interessen beherrschten World Wide Web. Das Buch deckt auf verständliche Weise die unterschiedlichen Methoden der Manipulation auf. Es zeigt, wie fremdgesteuerte Inhalte alle Internetnutzer betreffen, geht aber gleichzeitig auf mögliche Auswege und Lösungsmöglichkeiten ein. Als Plädoyer für ein nachhaltig unabhängiges Internet. Mit Illustrationen von Melanie Sotiris.

Nach Jahrzehnten des Immer-schneller, Immer-kleiner, Immer-billiger stößt der herkömmliche Computerchip an seine Grenzen. Forscher entwickeln stattdessen neue Computer, die ganz anders arbeiten als der klassische Rechner. Die neuen Konzepte basieren auf intelligenten Prozessen, die in der Natur – häufig im flüssigen Milieu – stattfinden. Diese "Suppenintelligenz" kommt daher gerade rechtzeitig: Sie erntet die Rechenkräfte der Natur. Die Suppenintelligenz erscheint in vielen Gestalten. Unser Begriff von "Computer" wird sich stark erweitern. Computer, die verdrahtet sind wie das Gehirn, werden atemberaubend schnell lernen, Muster erkennen und möglicherweise kreativ sein. Molekulare Rechner und Quantencomputer werden unbegreiflich komplexe Aufgaben lösen. Biocomputer werden in der Lage sein, im menschlichen Körper diffizile Diagnosen vorzunehmen, oder Ökosysteme im Gleichgewicht zu halten. Die Suppenintelligenz wird die nächste Stufe des Informationszeitalters zünden. Der Journalist und Physiker Dr. Christian J. Meier berichtet anschaulich von seinen Besuchen bei den Entwicklern der Suppenintelligenz in Deutschland, der Schweiz, Großbritannien und USA. Das Buch erklärt verständlich, warum klassische Rechner zwar sehr mächtig sind, aber dennoch an ihre Grenzen stoßen, und wie es die neuen Naturcomputer besser machen wollen.

Uncover surprises, risks, and potentially serious bugs with exploratory testing. Rather than designing all tests in advance, explorers design and execute small, rapid experiments, using what they learned from the last little experiment to inform the next. Learn essential skills of a master explorer, including how to analyze software to discover key points of vulnerability, how to design experiments on the fly, how to hone your observation skills, and how to focus your efforts. Software is full of surprises. No matter how careful or skilled you are, when you create software it can behave differently than you intended. Exploratory testing mitigates those risks. Part 1 introduces the core, essential skills of a master explorer. You'll learn to craft charters to guide your exploration, to observe what's really happening (hint: it's harder than it sounds), to identify interesting variations, and to determine what expected behavior should be when exercising software in unexpected ways. Part 2 builds on that foundation. You'll learn how to explore by varying interactions, sequences, data, timing, and configurations. Along the way you'll see how to incorporate analysis techniques like state modeling, data modeling, and defining context diagrams into your explorer's arsenal. Part 3 brings the techniques back into the context of a software project. You'll apply the skills and techniques in a variety of contexts and integrate exploration into the development cycle from the very beginning. You can apply the techniques in this book to any kind of software. Whether you work on embedded systems, Web applications, desktop applications, APIs, or something else, you'll find this book contains a wealth of concrete and practical advice about exploring your software to discover its capabilities, limitations, and risks.

The text Quantum Mechanics - An Introduction has found many friends among physics students and researchers so that the need for a third edition has arisen. There was no need for a major revision of the text but I have taken the opportunity to make several amendments and improvements. A number of misprints and minor errors have been corrected and a few clarifying remarks have been added at various places. A few figures have been added or revised, in particular the three-dimensional density plots in Chap. 9. I am grateful to several colleagues for helpful comments, in particular to Prof. R.A. King (Calgary) who supplied a comprehensive list of corrections. I also thank Dr. A. Scherdin for help with the figures and Dr. R. Mattiello who has supervised the preparation of the third edition of the book. Furthermore I acknowledge the agreeable collaboration with Dr. H. 1. Kolsch and his team at Springer-Verlag, Heidelberg.

From the bestselling author of The Theoretical Minimum, a DIY introduction to the math and science of quantum physics First he taught you classical mechanics. Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and associated mathematics of the strange world of quantum mechanics. In this follow-up to The Theoretical Minimum, Susskind and Friedman provide a lively introduction to this famously difficult field, which attempts to understand the behavior of sub-atomic objects through mathematical abstractions. Unlike other popularizations that shy away from quantum mechanics’ weirdness, Quantum Mechanics embraces the utter strangeness of quantum logic. The authors offer crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics, and each chapter includes exercises to ensure mastery of each area. Like The Theoretical Minimum, this volume runs parallel to Susskind’s eponymous Stanford University-hosted continuing education course. An approachable yet rigorous introduction to a famously difficult topic, Quantum Mechanics provides a tool kit for amateur scientists to learn physics at their own pace.

Welcome to the bizarre and dangerous world of Victorian London, a city teetering on the edge of revolution. Its people are ushering in a new era of technology, dazzled each day by new inventions. Airships soar in the skies over the city, whilst ground trains rumble through the streets and clockwork automatons are programmed to carry out menial tasks in the offices of lawyers, policemen and journalists. But beneath this shiny veneer of progress lurks a sinister side. For this is also a world where lycanthropy is a rampant disease that plagues the dirty whorehouses of Whitechapel, where poltergeist infestations create havoc in old country seats, where cadavers can rise from the dead and where nobody ever goes near the Natural History Museum. The Immorality Engine is the third in the Newbury and Hobbes series.

This book is an introduction to information and coding theory at the graduate or advanced undergraduate level. It assumes a basic knowledge of probability and modern algebra, but is otherwise self- contained. The intent is to describe as clearly as possible the fundamental issues involved in these subjects, rather than covering all aspects in an encyclopedic fashion. The first quarter of the book is devoted to information theory, including a proof of Shannon's famous Noisy Coding Theorem. The remainder of the book is devoted to coding theory and is independent of the information theory portion of the book. After a brief discussion of general families of codes, the author discusses linear codes (including the Hamming, Golary, the Reed-Muller codes), finite fields, and cyclic codes (including the BCH, Reed-Solomon, Justesen, Goppa, and Quadratic Residue codes). An appendix reviews relevant topics from modern algebra.

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.
