Quantum Coherence and Information
Seminar Schedule
This series of talks bearing on issues in quantum measurement theory, foundation and interpretation of quantum mechanics,  quantum decoherence and quantum-classical correspondence, quantum information and computation, is designed to assist graduate students beginning to do research in this newly developing interdisciplinary field.  Its nature will vary from reports of original research to review of recent papers of significance. It is hoped that theoretical discussions of issues and models will draw on current experiments in AMO (atom-field interaction, cavity ions) condensed matter (SQUID, Dots), molecular/nuclear (NMR) and nonlinear sciences (quantum chaos) related to the physics of quantum computer prototypes
