Quantum Computing Devices: Principles, Designs, and Analysis (Chapman & Hall/CRC Applied Mathematics and Nonlinear Science)

Description

One of the first books to thoroughly examine the subject, Quantum Computing Devices: Principles, Designs, and Analysis covers the essential components in the design of a "real" quantum computer. It explores contemporary and important aspects of quantum computation, particularly focusing on the role of quantum electronic devices as quantum gates. Largely self-contained and written in a tutorial style, this reference presents the analysis, design, and modeling of the major types of quantum computing devices: ion traps, cavity quantum electrodynamics (QED), linear optics, quantum dots, nuclear magnetic resonance (NMR), superconducting quantum interference devices (SQUID), and neutral atom traps. It begins by explaining the fundamentals and algorithms of quantum computing, followed by the operations and formalisms of quantum systems. For each electronic device, the subsequent chapters discuss physical properties, the setup of qubits, control actions that produce the quantum gates that are universal for quantum computing, relevant measurements, and decoherence properties of the systems. The book also includes tables, diagrams, and figures that illustrate various data, uses, and designs of quantum computing. As nanoelectronics will inevitably replace microelectronics, the development of quantum information science and quantum computing technology is imperative to the future of information science and technology. Quantum Computing Devices: Principles, Designs, and Analysis helps fulfill this need by providing a comprehensive collection of the most promising devices for the future. Review: Today's State of the Art - Still in only the most advanced laboratories the future of computing seems to lie in new technologies that will replace the current type of semi-conductors. These technologies, lumped together under the term Quantum Devices. For the first time, the leading reserchers from around the world have gotten together to produce a book containing all of the promising areas that are being worked on, summarizing the work up to date, and giving some indication of the direction of future research. Up until now the ever increasing speed of computers has been following Moore's law which states that the computing power of a CPU will double every 1.5 years at half the price. But in about nine more doublings there is a brick wall, the devices built into the chip will be one atom wide and you can't get any smaller than that with semi-conductors. The basic concepts of quantum computing go back to the 80's. But the actual construction of devices that could perform the basic tasks such as quantum logic gates has proven more difficult, There are several schemes that have shown promise, but each has stumbled over roadblocks and difficulties. In turn each has provided spin offs into both computing and other areas as well. Here in one book is the story of the state of the art.
