Book Description
Christopher G. Timpson provides the first full-length philosophical treatment of quantum information theory and the questions it raises for our understanding of the quantum world. He argues for an ontologically deflationary account of the nature of quantum information, which is grounded in a revisionary analysis of the concepts of information.

Book Description
This thesis explores several different aspects in theoretical quantum computing, including problems in application, implementation and fundamental theories. First, we investigate the spin bus problem. We primarily focus on the non-local multi-qubit entanglement state generation and unitary gate construction using the new type of gates we proposed, the mediated gates. We build a complete set of toolbox to solve and optimize this problem using all the different mediated gates spin bus could offer. Specifically, we compare the quantum circuit efficiency with the conventional serial gate implementation method using a nearest-neighbor SWAP gate and demonstrate that in most cases, using mediate gates through a spin bus will provide a significant improvement in terms of circuit depth. As a consequence, it provides a viable and robust solution to the challenges we face when considering scalability in quantum circuits. We then turn our attention to a specific implementation of encoded logical qubit, the exchange-only qubit in a semiconductor triple quantum dot. It has plenty of advantages compare to other encoded qubit, such as fast gate operations via pure electrical control, and robustness against global magnetic noise when encoding happens in decoherence free subspace, etc. We show that there are more things we could do to further improve the quality of gate operations on such encoded logical qubits. The general idea is similar as in the context of singlet-triplet qubits and hybrid qubits. One thing is to take full advantage of the true ``sweet spot'' of its energy level diagram as the optimal working point, which provides protection against charge noise. The other is that we could optimize the tunnable parameters in the pulse sequence by taking into account the knowledge we have about the device, such as the strength of nuclear field bath (for GaAs triple quantum dot) and the dephasing rate. Our result shows the upper bounds you could anticipate for specific gate operations using DC pulse sequences. Finally, we discuss a more theoretically fundamental problem in quantum computation, the property of two partite entanglement space. We calculate the separability probability in the high dimensional space of two rebits, two qubits, and two quaterbits using Monte Carlo Sampling methods. Our results match the analytical conjecture almost perfectly for such three systems. Our method of probing such problems provides a simple but efficient way to explore the geometrical structure of high dimensional two partite system, such as the distribution of physical, separable and entanglement states. And the connection between our numerical simulations and the analytical conjecture proposed earlier might imply something more fundamental yet to be uncovered.

Book Description
Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.

Book Description
By the year 2020, the basic memory components of a computer will be the size of individual atoms. At such scales, the current theory of computation will become invalid. "Quantum computing" is reinventing the foundations of computer science and information theory in a way that is consistent with quantum physics - the most accurate model of reality currently known. Remarkably, this theory predicts that quantum computers can perform certain tasks breathtakingly faster than classical computers – and, better yet, can accomplish mind-boggling feats such as teleporting information, breaking supposedly "unbreakable" codes, generating true random numbers, and communicating with messages that betray the presence of eavesdropping. This widely anticipated second edition of Explorations in Quantum Computing explains these burgeoning developments in simple terms, and describes the key technological hurdles that must be overcome to make quantum computers a reality. This easy-to-read, time-tested, and comprehensive textbook provides a fresh perspective on the capabilities of quantum computers, and supplies readers with the tools necessary to make their own foray into this exciting field. Topics and features: concludes each chapter with exercises and a summary of the material covered; provides an introduction to the basic mathematical formalism of quantum computing, and the quantum effects that can be harnessed for non-classical computation; discusses the concepts of quantum gates, entangling power, quantum circuits, quantum Fourier, wavelet, and cosine transforms, and quantum universality, computability, and complexity; examines the potential applications of quantum computers in areas such as search, code-breaking, solving NP-Complete problems, quantum simulation, quantum chemistry, and mathematics; investigates the uses of quantum information, including quantum teleportation, superdense coding, quantum data compression, quantum cloning, quantum negation, and quantum cryptography; reviews the advancements made towards practical quantum computers, covering developments in quantum error correction and avoidance, and alternative models of quantum computation. This text/reference is ideal for anyone wishing to learn more about this incredible, perhaps "ultimate," computer revolution. Dr. Colin P. Williams is Program Manager for Advanced Computing Paradigms at the NASA Jet Propulsion Laboratory, California Institute of Technology, and CEO of Xtreme Energetics, Inc. an advanced solar energy company. Dr. Williams has taught quantum computing and quantum information theory as an acting Associate Professor of Computer Science at Stanford University. He has spent over a decade inspiring and leading high technology teams and building business relationships with and Silicon Valley companies. Today his interests include terrestrial and Space-based power generation, quantum computing, cognitive computing, computational material design, visualization, artificial intelligence, evolutionary computing, and remote olfaction. He was formerly a Research Scientist at Xerox PARC and a Research Assistant to Prof. Stephen W. Hawking, Cambridge University.

Book Description
This book constitutes the thoroughly refereed post-conference proceedings of the 6th Conference on Theory of Quantum Computation, Communication, and Cryptography, TQC 2011, held in Madrid, Spain, in May 2011. The 14 revised papers presented were carefully selected from numerous submissions. The papers present new and original research and cover a large range of topics in quantum computation, communication and cryptography, a new and interdisciplinary field at the intersection of computer science, information theory and quantum mechanics.
