EmQM13 – An Action Principle for Cellular Automata and the Linearity of Quantum Mechanics
In recent years, it was realized that weak measurements on many copies of a system can be used to directly extract its quantum features. In a deterministic view of quantum theory, such as Bohmian mechanics, one can even acquire information that is normally inaccessible — for example, measuring simultaneously the position and momentum of a particle. This allows the direct measurement of Bohmian trajectories. I will discuss how the sub-quantum features revealed in these trajectories bring into focus the non-local nature of quantum theory and highlight its essential strangeness, as well as pave the way toward an understanding of the qualities of post-quantum theories.
Gregor Weihs is Professor of Photonics and Head of the Institute for Experimental Physics at the University of Innsbruck and an Associate of the University of Waterloo's Institute for Quantum Computing. While being on leave from his position in Vienna he spent two and a half years as Consulting Assistant Professor at Stanford University collaborating with the group of Yoshihisa Yamamoto (now at RIKEN) and Assistant Professor of Research at Tokyo University working on semiconductor quantum optics with Yasuhiko Arakawa's group. Gregor Weihs was DOC-fellow of the Austrian Academy of Sciences; he won the Appreciation Award of the Austrian Ministry of Science and Transport and the Loschmidt-Prize of the Chemical-Physical Society in Vienna. In 2007 he was awarded the Canada Research Chair in Quantum Photonics and in 2010 a Starting Grant by the European Research Council. In 2011 he was elected into the Austrian Academy of Sciences as a member of the Young Academy. His memberships include the Chemical-Physical, Austrian and American Physical Societies, the Canadian Association of Physicists, as well as the Optical Society of America. He is a fellow of the QIP program of the Canadian Institute for Advanced Research, and in addition currently holds grants from the European Research Council (ERC), and the Austrian Science Fund (FWF). In his research interests include fundamental physics both experimental and theoretical, quantum and semiconductor optics and quantum information. He currently focuses on novel sources of entangled photon pairs from nonlinear waveguides, via strong coupling in semiconductor microcavities, and from semiconductor quantum dots. He further does research is in quantum communication and the foundations of physics.

Professor and Associate Chair of Physics Ariel Caticha strongly believes that “physics is learned by doing.” To encourage students to join him on his voyage of discovery, the scholar – internationally recognized for his work on a “theory of X-ray and neutron scattering by thin film multilayers” and “capillary waveguides for soft X-rays and neutrons” – makes himself accessible to his undergraduate and graduate students both inside and outside the classroom. Caticha is also noted for his enthusiasm and for his ability to convey subtle concepts. These talents, combined with his accessibility, consistently earn him high marks from students who evaluate his teaching. To date, Caticha has mentored six students toward their doctoral dissertations. In addition, he has served as a reviewer of National Science Foundation research grant proposals. The author of numerous peer-reviewed and invited articles, Caticha also referees such scientific journals as Physical Review Letters, Journal of Physics, and Journal of the Optical Society of America.
