An engaging and accessible presentation of the most famous algorithms and applications of quantum computing The Joy of Quantum Computing introduces quantum computing succinctly, and with minimal mathematical formalism. Engagingly written—a feast for the reader’s inner nerd—it presents the most famous algorithms and applications of quantum computing and quantum information science, including the “killer apps,” Grover’s search algorithm, and Shor’s factoring algorithm. The only prerequisite is precalculus; readers need no knowledge of quantum physics. Matrices are relegated to the (completely optional) final two chapters. The book shows readers that quantum information science is about more than just high-speed calculations and data security. It is also about the fundamental meaning of quantum mechanics and the ultimate nature of reality. The Joy of Quantum Computing is suitable for classroom use or independent study by questing autodidacts. • Offers detailed explanations of quantum circuits, quantum algorithms, and quantum mysteries • Explains how to apply quantum information science to cryptography (and how Shor’s algorithm menaces classical cryptography) • Introduces the mystifying topics of quantum teleportation and the no-cloning theorem • Discusses Bell inequalities, which permit experimental tests of philosophical assumptions • Presents a simple model of quantum decoherence, shedding light on Schrödinger’s mysterious cat
Quantum Computing Explained
A self-contained treatment of the fundamentals of quantum computing This clear, practical book takes quantum computing out of the realm of theoretical physics and teaches the fundamentals of the field to students and professionals who have not had training in quantum computing or quantum information theory, including computer scientists, programmers, electrical engineers, mathematicians, physics students, and chemists. The author cuts through the conventions of typical jargon-laden physics books and instead presents the material through his unique "how-to" approach and friendly, conversational style. Readers will learn how to carry out calculations with explicit details and will gain a fundamental grasp of: * Quantum mechanics * Quantum computation * Teleportation * Quantum cryptography * Entanglement * Quantum algorithms * Error correction A number of worked examples are included so readers can see how quantum computing is done with their own eyes, while answers to similar end-of-chapter problems are provided for readers to check their own work as they learn to master the information. Ideal for professionals and graduate-level students alike, Quantum Computing Explained delivers the fundamentals of quantum computing readers need to be able to understand current research papers and go on to study more advanced quantum texts.
Quantum Computing for Everyone
An accessible introduction to an exciting new area in computation, explaining such topics as qubits, entanglement, and quantum teleportation for the general reader. Quantum computing is a beautiful fusion of quantum physics and computer science, incorporating some of the most stunning ideas from twentieth-century physics into an entirely new way of thinking about computation. In this book, Chris Bernhardt offers an introduction to quantum computing that is accessible to anyone who is comfortable with high school mathematics. He explains qubits, entanglement, quantum teleportation, quantum algorithms, and other quantum-related topics as clearly as possible for the general reader. Bernhardt, a mathematician himself, simplifies the mathematics as much as he can and provides elementary examples that illustrate both how the math works and what it means. Bernhardt introduces the basic unit of quantum computing, the qubit, and explains how the qubit can be measured; discusses entanglement—which, he says, is easier to describe mathematically than verbally—and what it means when two qubits are entangled (citing Einstein's characterization of what happens when the measurement of one entangled qubit affects the second as “spooky action at a distance”); and introduces quantum cryptography. He recaps standard topics in classical computing—bits, gates, and logic—and describes Edward Fredkin's ingenious billiard ball computer. He defines quantum gates, considers the speed of quantum algorithms, and describes the building of quantum computers. By the end of the book, readers understand that quantum computing and classical computing are not two distinct disciplines, and that quantum computing is the fundamental form of computing. The basic unit of computation is the qubit, not the bit.
