This book was released on 2009-02-19 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information theory lies at the heart of modern technology, underpinning all communications, networking, and data storage systems. This book sets out, for the first time, a complete overview of both classical and quantum information theory. Throughout, the reader is introduced to key results without becoming lost in mathematical details. Opening chapters present the basic concepts and various applications of Shannon's entropy, moving on to the core features of quantum information and quantum computing. Topics such as coding, compression, error-correction, cryptography and channel capacity are covered from classical and quantum viewpoints. Employing an informal yet scientifically accurate approach, Desurvire provides the reader with the knowledge to understand quantum gates and circuits. Highly illustrated, with numerous practical examples and end-of-chapter exercises, this text is ideal for graduate students and researchers in electrical engineering and computer science, and practitioners in the telecommunications industry.

Available in PDF, EPUB and Kindle. Book excerpt: Quantum computers are hypothetical quantum information processing (QIP) devices that allow one to store, manipulate, and extract information while harnessing quantum physics to solve various computational problems and do so putatively more efficiently than any known classical counterpart (5). Physical objects as they are, QIP devices are subject to the laws of physics. No doubt, the application of these laws is error-free, but noise - be it external influences or hardware imprecisions - can sometimes cause a mismatch between what the QIP device is supposed to do and what it actually does. In recent years the elimination of noise that result from external disturbances or from imperfect gates has become the "holy grail" within the quantum computing community, and a worldwide quest for a large scale, fault-tolerant, and computationally superior QIP device is currently taking place. Whether such machines are possible is an exciting open question, yet the debate on their feasibility has been so far rather ideological in character (45) (66)(110) (162). Remarkably, philosophers of science have been mostly silent about it: common wisdom has it that philosophy should not intervene in what appears to be (and is also presented as) an engineering problem, and besides, the mathematics employed in the theory of fault-tolerant quantum error correction (FTQEC henceforth) is rather daunting. It turns out, however, that behind this technical veil the central issues at the heart of the debate are worthy of philosophical analysis and, moreover, bear strong similarities to the conceptual problems that have been saturating a field quite familiar to philosophers, namely the foundations of statistical mechanics (SM henceforth). Reconstructing the debate on FTQEC with statistical mechanical analogies, this book aims to introduce it to readership outside the quantum computing community, and to take preliminary steps towards making it less ideological and mor

This book was released on 2019-04-27 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation explores several topics pertaining to quantum computation and information theory. First, we discuss the distinction between entangled and separable states from a geometric point of view. In particular, we construct the ellipsoid of smallest volume that bounds the set of separable states for systems of $n$ qubits, although the results generalize easily to larger spaces. This ellipsoid serves as an approximation of the boundary between separable and entangled states. Notably, we show that when restricted to pure states all separable states lie on the ellipsoid boundary, and all entangled states lie outside. We demonstrate that this distinguishing power motivates an entanglement measure on pure states. For 2 qubits, this measure can be written in a particularly convenient form, while for 3 or more qubits the ellipsoid structure provides a natural weighting of entanglement shared between subsystems of varying size. We then address classical models of quantum noise. Though the classical noise models are not fully general, it is known that certain classes of quantum noise can be realized classically. In particular, dephasing noise can always be simulated classically. For a single qubit, we explicitly construct classical models to simulate arbitrary dephasing noise. For two qubits, we construct classical models that reproduce a subset of the dephasing noise; these models can be combined to create more complicated dephasing behavior. Additionally, we show that depolarizing noise is classical for quantum systems of arbitrary dimension. Lastly we discuss error correction. Motivated by experimental capabilities and limitations of neutral atom qubits, we explore the practical possibility of measurement-free error correction. For three well known error correction codes---the bit-flip, Bacon-Shor, and Steane codes---we adapt standard measurement-based procedures to measurement-free circuits on neutral atom systems. In particular, we present a novel syndrome extraction technique to achieve fault-tolerance. Using numerical simulation we estimate first-level depolarizing thresholds for these circuits. We find that simulating realistic conditions for the bit-flip, Bacon-Shor, and Steane codes produced error thresholds of $\pth \approx 10^{-2}$, $10^{-3}$, and $10^{-4}$, respectively. Encouragingly, these results are within the range of expected neutral atom capabilities and compare well to measurement-based threshold values.

This book was released on 2012-12-06 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written to conclude the NATO Advanced Research Workshop "Quantum Noise in Mesoscopic Physics" held in Delft, the Netherlands, on June 2-4, 2002. The workshop was co-directed by M. Reznikov of Israel Institute of Technology, and me. The members of the organizing committee were Yaroslav Blanter (Delft), Chirstopher Glattli (Saclay and ENS Paris) and R. Schoelkopf (Yale). The workshop was very successful, and we hope that the reader will be satisfied with the scientific level of the present book. Before addressing scientific issues I find it suitable to address several non-scientific ones. The workshop was attended by researchers from many countries. Most of them perform their activities in academic institutions, where one usually finds the necessary isolation from the problems and sores of the modem world. However, there was a large group of participants for which such isolation was far from perfect. War, hatred, and violence rage just several miles away of their campuses and laboratories, poisoning everyday life in the land of Israel.
