"Quantum Computing" are reinventing the basics of computer science and information theory in a manner consistent with quantum physics - the most accurate model of reality currently known. Remarkably, this theory predicts that quantum computers can perform certain tasks thrilling faster than classical computers? The second edition of this widely anticipated Exploration in Quantum Computing explain this development is growing at a modest, and describes the key technological hurdles that must be overcome to make quantum computers a reality. It is easy to read, time tested, and comprehensive textbook provides a fresh perspective on the ability of quantum computers, and supplies readers with the tools necessary to make their own foray into this exciting field. Topics and features: each chapter concludes with exercises and a summary of the material covered; provides an introduction to basic mathematical formalism of quantum computing and quantum effects that can be used for non-classical computation; discusses the concept of quantum gates, involving power, quantum circuits, quantum Fourier , wavelet, and cosine transform, and quantum universality, computability, and complexity, examining the potential of quantum computer applications in various fields such as search, code-breaking, problem solving NP-Complete, quantum simulation, quantum chemistry, and mathematics; investigate the use of quantum information, including quantum teleportation, superdense coding, quantum data compression, quantum cloning, quantum negation, and quantum cryptography; review progress made towards a practical quantum computer, which includes the development of quantum error correction and avoidance, and alternative model of quantum computation.
