The contributors of this volume are working at the forefront of various realizations of quantum computers. They survey the recent developments in each realization, in the context of the DiVincenzo criteria, including nuclear magnetic resonance, Josephson junctions, quantum dots, and trapped ions. There are also some theoretical contributions which have relevance in the physical realizations of a quantum computer. This book fills the gap between elementary introductions to the subject and highly specialized research papers to allow beginning graduate students to understand the cutting-edge of research in the shortest possible time. Sample Chapter(s). Chapter 1: DiVincenzo Criteria and Beyond (537 KB). Contents: DiVincenzo Criteria and Beyond (M M Salomaa & M Nakahara); Single-Electron Charge and Spin Qubit in Semiconductor Quantum Dots (T Fujisawa); Superconducting Quantum Computing: Status and Prospects (F K Wilhelm & K Semba); Controlling Three Atomic Qubits (H Hnffer et al.); Liquid-State NMR Quantum Computer: Hamiltonian Formalism and Experiments (Y Kondo et al.); Optical Quantum Computation (K Nemoto & W J Munro). Readership: Graduates students and researchers in physics."

An introduction and comprehensive survey of the main issues in mesosocopic physics. Topics covered include quantum Hall effects, transport through quantum wires and dots, coherence in mesoscopic systems, spintronics, disordered systems, and solid state quantum computation. Some contributions are dedicated to the connections between nanoscience and biophysics and quantum optics. Although the topics mentioned have many aspects in common, they span a wide area of physics. It is therefore especially important to provide a broad view of this rapidly expanding field. Thanks to the excellent presentations, the book will be found suitable both for young researchers who want to enter the field and stimulating for more experienced scientists.

The NATO Advanced Research Workshop took place from 29 May to I June 2000 in the picturesque Hungarian town of Pecs, 220 km south of Budapest. The main goal of the workshop was to review and promote experimental and theoretical research on the problem of Kondo-type scatteringofthe electrons in systems ofreduced dimensionalities. 53 regular participants and 7 observers from 17 different countries attended the workshop. The Kondo effect has been a topic ofintense interest for many years, due in part to its relevance to a variety of other branches of condensed matter physics. In addition to the best known example of magnetic impurities in noble metals, the physics of the Kondo effect is important in many areas of current research, including heavy-fermion physics, correlated electron systems, and high-temperature superconductivity. Of central importance in this problem is the interaction of conduction electrons in the metal with individual magnetic impurities, an interaction which also mediates the interaction ofthe impurities with each other.

Quantum mechanical laws are well documented at the level of a single or a few atoms and are here extended to systems containing 102 to 1010 electrons - still much smaller than the usual macroscopic objects, but behaving in a manner similar to a single atom. Besides the purely theoretical interest, such systems pose a challenge to the achievement of the ultimate microelectronic applications. The present volume presents an up-to-date account of the physics, technology and expected applications of quantum effects in solid-state mesoscopic structures. Physical phenomena include the Aharonov-Bohm effect, persistent currents, Coulomb blockade and Coulomb oscillations in single electron devices, Andreev reflections and the Josephson effect in superconductor/normal/superconductor systems, shot noise suppression in microcontacts and contact resistance quantisation, and overall quantum coherence in mesoscopic and nanoscopic structures related to the emerging physics of quantum computation in the solid-state environment.

Many mesoscopic systems display `adaptive' behaviour - changes in some physical property that results from a small change in an internal or external driving force. There is a kind of progression in adaptive phenomena, from quantum mesoscopics to complex, evolved cooperative systems and large scale events like turbulence. The field of mesoscopic magnetism, especially quantum coherence and quantum tunnelling in spin systems, and the coupling between mesoscopic magnetism and mesoscopic transport is currently a very active area of solid state physics. `Dephasing' is an important concept in mesoscopic systems like these. A basic question is the limit at which quantum mechanics breaks down and what it can be replaced with. Another interesting crossover is that between complexity and large excursions or events, with turbulence as a prototype example. The book also contains a discussion of finance. Qualitatively speaking, turbulence and financial markets are apparently similar, so our understanding of turbulence may be relevant to understanding price fluctuations.

Future high-tech applications such as nanotechnology require a deep understanding of the physics of mesoscopic systems. These systems form a bridge between macroscopic systems governed by classical physics and microscopic systems governed by quantum physics. This introduction discusses a variety of typical surface, optical, transport, and magnetic properties of mesoscopic systems with reference to many experimental observations. It is written for physicists, materials scientists and engineers who want to stay abreast of current research or high-tech development.
