Ingemar Bengtsson is a professor of physics at Stockholms Universitet. After gaining a Ph.D. in Theoretical Physics from the
Goeteborgs universitet (1984), he held post-doctoral positions at CERN, Geneva, and the Imperial College of Science, Technology
and Medicine, University of London. He returned to Goeteborg in 1988 as a research assistant at Chalmers tekniska hoegskola,
before taking up a position as Lecturer in Physics at Stockholms Universitet in 1993. He was appointed Professor of Physics
in 2000. Professor Bengtsson is a member of the Swedish Physical Society and a former board member of its Divisions for Particle
Physics and for Gravitation. His research interests are related to geometry, in the forms of classical general relativity
and quantum theory. Karol Zyczkowski is a professor at the Institute of Physics, Uniwersytet Jagiellonski, Krakow, Poland,
and also at the Center for Theoretical Physics, Polska Akademia Nauk, Warsaw. He gained his Ph.D. and habilitation in theoretical
physics at Uniwersytet Jagiellonski, and has followed this with a Humboldt Fellowship in Essen, a Fulbright Fellowship at
the University of Maryland, College Park, and a visiting research position at the Perimeter Institute for Theoretical Physics,
Ontario. He has been docent at the Academy of Sciences since 1999 and full professor at Uniwersytet Jagiellonski since 2004.
Professor Zyczkowski is a member of the Polish Physical Society and Academia Europaea. He works on quantum information, dynamical
systems and chaos, quantum and statistical physics, applied mathematics, and theory of voting.
