Scalable Quantum Computers. Paving the Way to Realization. With figures

Quantum computers hold the promise of solving problems that would otherwise be intractable with conventional computers. Some prototypes of the simplest elements needed to build a quantum computer have already been implemented in the laboratory. The efforts now concentrate on combining these elements into scalable systems. In addition, alternative routes to creating large scale quantum computers are continuously being developed.
This volume gives a cross-section of recent achievements in both the theory and the practical realization of quantum computing devices. Samuel L. Braunstein (Reader, University of Wales, Bangor, and editor of the book "Quantum Computing - Where do we want to go tomorrow") and Hoi-Kwong Lo (Chief Scientist, MagiQ Technologies, Inc., NY) invited experts across many disciplines involved in the development of quantum computers to review their proposals in a manner accessible to the non-expert.
Breaking with tradition, this book not only contains proposals, but a set of independent expert evaluations of these ideas as well. As a by-product this volume facilitates a comparison between the widely varying disciplines covered, including: ion traps, cavity quantum electrodynamics, nuclear magnetic resonance, optical lattices, quantum dots, silicon systems, superconductivity and electrons on helium.

Dr. Hoi-Kwong Lo
Senior Vice President Research and development of MagiQ Technologies, Inc., New York;
Hoi-Kwong Lo was born in Hong Kong in 1967. He obtained his B. A. in Mathematics (Triple First Class Honors) from Trinity College, Cambridge University, UK in 1989 and his M.S. and Ph.D. in Physics from the California Institute of Technology, Pasadena, USA in 1991 and 1994 respectively. After getting his Ph.D., he became a Member of the Institute for Advanced Study, Princeton, NJ.
From 96 to 99, he was with the Hewlett-Packard Laboratories, Bristol, UK, first as a Research Consultant and then as a Senior Member of Technical Staff. He is currently Senior Vice President, Research and Development of MagiQ Technologies, Inc. This is the first quantum computing start-up with a stated goal of building a "quantum Internet."
His current research interests include quantum computation and also cryptography. He is one of the persons who have demonstrated the impossibility of a whole class of quantum cryptographic schemes including quantum bit commitment. This result has been widely reported in the scientific press including Science and Science News. Recently, in a paper in "Science", he and his colleague have given a rigorous proof of the security of quantum key distribution, the most well-known application of quantum cryptography. This result has been reported in a "perspectives" article in Science. He has co-edited a textbook on quantum computation and information, which has been favorably reviewed in Nature, and he is the main inventor of a US patent.
