This summer several workshops will take place July 17-23 (2006) at Oxford University: * NEW MODELS OF QUANTUM INFORMATICS * AXIOMATICS FOR QUANTUM MECHANICS * TENSORS KNOTS AND BRAIDS IN LOGIC AND PHYSICS * QUANTUM PROGRAMING LANGUAGES (QPL IV) The whole event will take place under the name ``CATS, KETS and CLOISTERS'': * http://se10.comlab.ox.ac.uk:8080/FOCS/CKCinOXFORD_en.html [SURVEYS/TUTORIALS:] Each workshop will include tutorial and/or survey talks. Preliminary informal contacts concerning have confirmed several people willing to provide these survey/tutorial lectures, including Samson Abramsky (Oxford), Richard Jozsa (Bristol) and Sam Lomonaco Jr (UMBC), among others. Topics under consideration include: measurement-based quantum computation, topological quantum computation, simulations of quantum computations, knots and braids in logic, quantum geometry and topology, categorical algebra for quantum mechanics, and semantics for quantum computing. [CALL FOR CONTRIBUTIONS:] The call for QPL IV is available at: * http://www.mathstat.dal.ca/~selinger/qpl2006/ We invite you to propose contributions for the three other workshops, either by submitting a short description, short abstract, extended abstract or full paper. These contributions will then be considered by the Program Committee: Jens Eisert (Imperial College, UK) Richard Jozsa (University of Bristol, UK) Samuel Lomonaco Jr. (UMBC, Maryland, US) Prakash Panangaden (McGill University, CA) Phil Scott (University of Ottawa, CA) Samson Abramsky (University of Oxford, UK) Bob Coecke (University of Oxford, UK) Relevant proposals for surveys/tutorials are also still welcome. Preference will be given to talks which are accessible beyond the boundaries of the distinct workshops. The three workshops should indeed be conceived as ``themes'' within a bigger event. Slots will be allocated to speakers to some extend on a first-come-first-serve base, subject to a quality check and ``sufficiently broad relevance'' check by the PC. Please send your contributions to: * bob.coecke@comlab.ox.ac.uk [POSTER SESSION:] Students and other young researchers in particular are encouraged to propose posters, which will be displayed in the workshop area throughout the whole event, and to which a session will be dedicated. [PRACTICALITIES:] The local organizing committee consists of: Samson Abramsky (Computing) Dan Browne (Physics) Bob Coecke (Computing) Hilary Priestley (Mathematics) Oxford is a pleasant place to visit during the summer, with many things to see (including London, only an hour by train), and a wealth of tourist attractions and beautiful country-side conveniently accessible. * http://www.oxfordcity.co.uk/ Oxford has a wide variety of places to stay, including both junior and senior College Accomodation, Hotels, Hostels, and Bed and Breakfasts (B&Bs) and Guest Houses. We would in particular recommend the B&Bs and Guest Houses since they tend to be much cheaper than hotels, and the British breakfast keeps you going for the whole day.
