Quantum Information, Computation and Logic: Exploring New Connections  2005
Both quantum logic (QL) and quantum information (QI) are based on viewing quantum mechanics in terms of concepts closely tied to information, so QL, should be closely connected to QI. On the whole, these two research fields are pursued by separate communities and so a closer collaboration is likely to yield significant insights into both. While taking a broad view of both fields, the workshop will focus on areas that we feel are most likely to spark significant collaboration and new research initiatives. 
Summer School: Strings, Gravity & Cosmology  2005
This will be the third in an ongoing series of annual summer schools in theoretical physics held in Canada. The first and second editions of these schools will be held at the University of British Columbia. These schools are intended to educate graduate students and young researchers on current developments in string theory and its interface with gravity and cosmology. Our intent in organizing the 2005 school at the Perimeter Institute at this time is that it will also offer the students the opportunity to attend the Strings 2005 conference, which will be held in Toronto in the week immediately following the school. 
Perimeter/UofT/CITA MiniWorkshop  2005
This miniworkshop will be the next of an ongoing series of oneday meetings between researchers at Perimeter, CITA and University of Toronto. These meetings are held to share new ideas and encourage interactions in our common fields of interest: superstrings, cosmology, particle theory and quantum gravity. 
Thematic Program on The Geometry of String Theory 2004  2005: String Phenomenology
String phenomenology is an emerging research area in the rich interdisciplinary boundaries of string theory, particle physics, and cosmology. Although research in string phenomenology is motivated by physical questions, progress often comes from connections to more formal and mathematical aspects of string theory. These connections include: *How does the Standard Model of particle physics arise from string theory?: CalabiYau manifolds, G2 manifolds, brane worlds, orientfolds, intersecting Dbranes, warped compactifications, flux compactifications *Can string theory provide a realistic cosmology?: brane cosmology, tachyon condensation, string field theory, decay of unstable branes, thermodynamics of strings and branes, Hagedorn temperature, models of inflation, timedependent backgrounds *What are the experimental signatures of string theory?: brane worlds, extra dimensions, signatures of short distance physics from early universe cosmology, cosmic strings It is truly an exciting time in cosmology where experiments have produced and are continuing to yield an abundance of precision data. Similarly, collider experiments at Fermilab, SLAC and CERN, as well as precision lowenergy experiments, have the potential to make remarkable new discoveries in particle physics in the next five years. Hence string phenomenology is both a timely and exciting topic of a workshop in 2005.

Thematic Program on The Geometry of String Theory 2004  2005: Mirror Symmetry
This meeting will be an international gathering of leading researchers to discuss the latest developments in our understanding of "mirror symmetry", a surprising relation that can exist between two CalabiYau manifolds. It happens that two such geometries may look very different, but are nevertheless equivalent when employed as hidden dimensions in string theory. Mirror symmetry has become a very powerful tool in both physics and mathematics. 
Workshop on Quantum Gravity in the Americas: Status and future directions  2004
The goal of the workshop is to bring together Quantum Gravity researchers working in the Americas to share their approaches and results, draw connections between research efforts, develop a broader perspective on the issues, focus on outstanding problems, foster an interactive community, and set objectives for future research. This workshop is a followingup of the workshop organized in January in Mexico. 
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 informationprocessing protocols and physical parameter estimation.
