WOOTTERS 299 Preface This book is a collection of papers given by invited speakers at the AMS Spe- cial Session on Quantum Computation and Information held at the Annual Meeting of the American Mathematical Society in Washington, DC, January 19-21, 2000. This AMS Special Session was held in conjunction with the AMS Short Course on Quantum Computation, January 17-18, 2000, which has been published sepa- rately as the AMS PSAPM Volume 58 entitled "Quantum Computation: A Grand Mathematical Challenge for the Twenty-First Century and the Millennium." This Special Session, together with its accompanying Short Course, was the first time at an AMS meeting that the new and emerging discipline of quantum information science was formally introduced to the AMS community. It is hoped that this event, together with the two books recording this occasion, will act as a catalyst to encourage members of the mathematical community to take advantage of the many mathematical research opportunities arising from the Grand Challenge of Quantum Information Science. This book was partially supported by the Defense Advanced Research Projects Agency (DARPA) and Air Force Materiel Command USAF under agreement num- ber F30602-01-0522, by Army Research Office (ARO) Grant #P-38804-PH-QC, by the National Institute of Standards and Technology (NIST), and by L-0-0-P Fund No. 2000WADC. The editors thank UMBC and ARL for support in this endeavor. Thanks are also due to Jekkin Shah for spending many hours transforming the papers contributed to this volume into AMS LaTeX. Moreover, the editors thank the staff of the American Mathematical Society for their editorial support. Finally, thanks are due to all the AMS Session participants whose efforts and contributions made all this possible. Samuel J. Lomonaco, Jr. Howard E.

This award was presented at the AMS Special Session on Quantum Computation and Information held at the Annual Meeting of the American Math- ematical Society in Washington, DC, in January 2000. Description of the Pot de Vin Prize The Pot de Vin Prize is an award coveted by Nobel Laureates and Fields Medalists. It was established to bribe (FR, pot de vin) major contributors to the field of quantum computation and quantum information into giving an invited talk. All Nobel Laureates and Fields Medalists are automatically disqualified from receiving the prize. The Pot de Vin Prize is sponsored by the L-0-0-P Fund. vii List of Participants The First Special Session on Quantum Computation and Information Annual Meeting of the American Mathematical Society Washington, DC January 19-21, 2000 Paul Benioff Gianfranco F.
