Workshop on Reference Frames and Superselection Rules in Quantum Information Theory - 2004
Over the past five years, there has been much interest in a new kind of "unspeakable" quantum information which is to regular quantum information what a classical clock or gyroscope is to a classical message. While the latter is indifferent to the physical nature of the information carriers, the former requires the carrier to have a particular degree of freedom -- a spatial orientation in the case of a gyroscope, or a natural oscillation in the case of a clock. Systems serving this purpose are referred to generically as reference frames, and constitute a quantifiable resource in quantum information theory. They play a central role in the tasks of direction and frame alignment, phase estimation, clock synchronization, and global positioning. The community has only just begun a systematic study of how this resource can be manipulated, quantified, and used optimally in both information-processing protocols and physical parameter estimation. -
Perimeter Institute Quantum Discussions
This series consists of weekly discussion sessions on foundations of quantum theory and quantum information theory. The sessions start with an informal exposition of an interesting topic, research result or important question in the field. Everyone is strongly encouraged to participate with questions and comments. -
Strings Group Meeting
These talks are informal discussion in the area of Superstring Theory. Formal talks are part of the Strings Seminar series above -
International Loop Quantum Gravity Seminar
The International Loop Quantum Gravity Seminar series is held via teleconference among the main international research groups in loop quantum gravity. Slides are distributed in advance of the discussion and audio is posted after the seminar on the ILQG website. -
Cosmology Talks
This series consists of discussions in the areas of Cosmology and Particle Physics. -
Tensor Network
This series consists of occasional seminars on Tensor Networks, ranging from algorithms to their application in condensed matter, quantum gravity, or high energy physics. Each seminar starts with a gentle introduction to the subject under discussion. Everyone is strongly encouraged to participate with questions and comments. -
Particle Group Meeting
This series consists of talks in the area of Condensed Matter. -
Administrative
Use this category for Administrative events that are not Health, Wellness or Social. Subcategories are by Department (as necessary), e.g. Advancement Events. Event Type is usually Lecture but multi-day events use Event Types Conference or Meeting. Events in this category are listed on Kiosks and PION. Integration to the Perimeter website is off (except when Event is Public). Visibility is to all Admin Groups. Event Creation also available to all Admin Groups. -
Health, Wellness & Social
Use this category for Health, Wellness & Social Events for PI Residents (please include events of interest to ALL PI Residents). Event Type is usually Lecture but multi-day events can use event types Conference or Meeting. Events in this category are listed on Kiosks and PION and on the Perimeter website (when Event is Public). Visibility is to all Admin Groups and all Researchers and most Visitors. Event Creation also available to all Admin Groups, all Researchers and most Visitors.
