Essential Quantum Cases

A concise, lucid development of the fundamental structure of quantum mechanics from a thoroughly modern perspective. Focusing on physical and mathematical understanding, with over 60 problems, this compact introduction is invaluable for students and researchers in physics and other fields where quantum mechanics plays an important role.

Covering some of the most exciting trends in quantum optics - quantum entanglement, teleportation, and levitation - this textbook is ideal for advanced undergraduate and graduate students. The book journeys through the vast field of quantum optics following a single theme: light in media. A wide range of subjects are covered, from the force of the quantum vacuum to astrophysics, from quantum measurements to black holes. Ideas are explained in detail and formulated so that students with little prior knowledge of the subject can follow them. Each chapter ends with several short questions followed by a more detailed homework problem, designed to test the reader and show how the ideas discussed can be applied. Solutions to homework problems are available at www.cambridge.org/9780521869782.

This textbook on quantum mechanics has been designed for use in two-semester undergraduate courses. It describes the basic concepts of quantum mechanics, explains the use of the mathematical formalism and provides illustrative examples of both concepts and methods. Although the aim is to enable students to master the use of quantum mechanics as a tool, the author also discusses the meaning of quantum concepts. To this end the book contains a variety of relevant examples, worked out in considerable detail, as well as a substantial number of pertinent problems and exercises. The latter will be extremely helpful, if not essential, for gaining a deep understanding and command of the subject. This book is based on the author's thirty years experience of teaching the subject.

Explore the principles and practicalities of quantum computing Key Features Discover how quantum computing works and delve into the math behind it with this quantum computing textbook Learn how it may become the most important new computer technology of the century Explore the inner workings of quantum computing technology to quickly process complex cloud data and solve problems Book DescriptionQuantum computing is making us change the way we think about computers. Quantum bits, a.k.a. qubits, can make it possible to solve problems that would otherwise be intractable with current computing technology. Dancing with Qubits is a quantum computing textbook that starts with an overview of why quantum computing is so different from classical computing and describes several industry use cases where it can have a major impact. From there it moves on to a fuller description of classical computing and the mathematical underpinnings necessary to understand such concepts as superposition, entanglement, and interference. Next up is circuits and algorithms, both basic and more sophisticated. It then nicely moves on to provide a survey of the physics and engineering ideas behind how quantum computing hardware is built. Finally, the book looks to the future and gives you guidance on understanding how further developments will affect you. Really understanding quantum computing requires a lot of math, and this book doesn't shy away from the necessary math concepts you'll need. Each topic is introduced and explained thoroughly, in clear English with helpful examples.What you will learn See how quantum computing works, delve into the math behind it, what makes it different, and why it is so powerful with this quantum computing textbook Discover the complex, mind-bending mechanics that underpin quantum systems Understand the necessary concepts behind classical and quantum computing Refresh and extend your grasp of essential mathematics, computing, and quantum theory Explore the main applications of quantum computing to the fields of scientific computing, AI, and elsewhere Examine a detailed overview of qubits, quantum circuits, and quantum algorithm Who this book is for Dancing with Qubits is a quantum computing textbook for those who want to deeply explore the inner workings of quantum computing. This entails some sophisticated mathematical exposition and is therefore best suited for those with a healthy interest in mathematics, physics, engineering, and computer science.

Der Autor dieses Lehrbuchs ist seit über 25 Jahren Dozent für Quantenmechanik in den Fachrichtungen Elektrotechnik und Informatik. Das Fachbuch ist wissenschaftlich fundiert und gut geschrieben, überzeugt durch eine ausgewogene Darstellung notwendiger formaler Mathematik und Text. Die Einführung fasst die Grundkonzepte der klassischen Physik zusammen und stellt einiger ihrer Versäumnisse heraus, die sich aus Phänomenen in Verbindung mit der Lichttechnik ergeben. Diese werden in den darauffolgenden drei Kapiteln ausführlich analysiert. Kapitel 5 geht über das Dualitätsprinzip hinaus und erläutert die Partikelkonzepte der Quantenmechanik sowie deren Folgen für die Elektrotechnik. In den Kapiteln 6 bis 8 werden die mathematischen Grundkonstruktionen beschrieben, mit denen sich der Zustand von Partikeln und deren Eigenschaften ableiten und vorhersagen lassen. Die beiden weiteren Kapitel zeigen zwei Beispiele hierfür mit Anwendungen von LEDs, Infrarotdetektoren, Quantenkaskadenlasern, Zener-Dioden und Flash-Speichern. In den letzten Kapiteln werden die Folgen der Quantenmechanik für die chemischen Eigenschaften von Atomen und anderen, aus vielen Elektronen bestehenden Systemen erörtert, abgerundet durch einen kurzen Einblick in die möglichen Hardwarekomponenten für die Quanteninformationsverarbeitung. Zu den vielfältigen didaktischen Merkmalen gehören auch Lernziele, Kapitelzusammenfassungen, Fragen zur Selbstüberprüfung sowie Problemlösungen. In den beiden Anhängen sind die notwendigen Kenntnisse der klassischen Physik und Mathematik zusammengefasst.

Quantum physics says that God can exist! With quantum science explained in simple English, here is the unequivocal connections between science and God people have been wanting for hundreds of years. Whether atheist, agnostic, or believer in God, be prepared to be awestruck by how science supports the possibility that God exists. The advanced branch of science known as quantum physics is responsible for computers, cell phones, satellites, microwave ovens, MRI technology, in fact every modern convenience, and yet most people know nothing about this field of science. But it also comes with amazing characteristics that both explain and support a creator God as written in the Bible. If you thought you've heard every angle on proving God's existence, you will find yourself dumbfounded on this new information. Every major quantum and string theory phenomena described in this book aligns with a God concept and helps to bring in-depth answers to some of the toughest questions asked by the most ardent atheists and inquisitive agnostics. This book is also for the least and most passionate of believers in God. If God created the universe then God also created all the laws of physics, the rules by which the universe abides. This book is for those who love science and see God all around. It is for those who think logically and want some of their longing questions addressed: How can there be a Big Bang 13.8 billion years ago and yet God created the universe only 6-10,000 years ago? How can God know my every thought and of all 7 billion people at every second? How can God know everything that has and will happen and yet be surprised of someone's decision? and more. A Quantum Case for God introduces the God Model, an interpretation of how the universe works and challenges this model against all the current leading scientific models. The God Model is by far the most comprehensive model in the challenge. Read this book and see first hand how the universe works at the sub-atomic level and how God is serious business within the laws of physics.

This comprehensive textbook on the rapidly advancing field introduces readers to the fundamental concepts of information theory and quantum entanglement, taking into account the current state of research and development. It thus covers all current concepts in quantum computing, both theoretical and experimental, before moving on to the latest implementations of quantum computing and communication protocols. It contains problems and exercises and is therefore ideally suited for students and lecturers in physics and informatics, as well as experimental and theoretical physicists in academia and industry who work in the field of quantum information processing. The second edition incorporates important recent developments such as quantum metrology, quantum correlations beyond entanglement, and advances in quantum computing with solid state devices.
