THE FIELDS INSTITUTE FOR RESEARCH IN MATHEMATICAL SCIENCES
20th ANNIVERSARY YEAR

Workshop on Mathematical Methods of
Quantum Tomography

February 19-22, 2013

Fields Institute, 222 College St.,Toronto


Organizers:
Hubert de Guise (Lakehead)
Berthold-Georg Englert (National University of Singapore)
Zdenek Hradil (Palacky University)
Gerd Leuchs (Max Planck Institute for the Science of Light)
Luis L. Sanchez-Soto (
Complutense University Madrid)

The objective in quantum tomography is to reconstruct the density matrix of a quantum state using “probes” (theoretical or experimental). The density matrix is a generalization of the quantum state vector that evolves following the Schrödinger equation of quantum mechanics. The solution to problems in this field are also of interest beyond the immediate quantum tomographic community as they are essential for a better understanding of quantum information processes and the prospective construction of a quantum computer. The objective of the Workshop is to gather experts and students working in the development and applications of mathematical tools related to quantum tomography and related problems.

Overview
We hope to foster new insights and different perspectives through this Workshop where researchers from a variety of backgrounds and expertise can exchange ideas in the informal atmosphere of a workshop. In line with this objective, the workshop will schedule a few morning talks and a significant portion of the program will be reserved for discussion sessions.

Posters
Participants wishing to present a poster will be able to indicate so at the time of registration. Some students who present a poster may be invited to submit their results for peer reviewed publication in the Canadian Journal of Physics.

Julian Schwinger Foundation
