CALL FOR PAPERS The 12th International Workshop on Quantum Physics and Logic (QPL) July 13-17, Oxford, United Kingdom http://www.cs.ox.ac.uk/qpl2015 The 12th International Workshop on Quantum Physics and Logic (QPL) will take place at the Department of Computer Science of the University of Oxford between Wednesday 15 and Friday 17 July, 2015. The workshop will be preceded by tutorials on Monday 13 and Tuesday 14 July 2015. This workshop brings together researchers working on mathematical foundations of quantum physics, quantum computing, spatio-temporal causal structures, and related areas such as computational linguistics. Of particular interest are topics that use logical tools, ordered algebraic and category-theoretic structures, formal languages, semantical methods and other computer science methods for the study of physical behaviour in general. Previous QPL events were held in Kyoto (2014), Barcelona (2013), Brussels (2012), Nijmegen (2011), Oxford (2010), Oxford (2009), Reykjavik (2008), Oxford (2006), Chicago (2005), Turku (2004), and Ottawa (2003). INVITED SPEAKERS Paul Busch (University of York) Dan Browne (University College London) Chris Douglas (University of Oxford) TUTORIALS Paul Busch (University of York): Quantum uncertainty Dan Browne (University College London): Teleportation and measurement- based computation Oscar Dahlsten (University of Oxford): Entropy and majorisation in generalised probabilistic theories Pawel Sobocinski (University of Southampton): Graphical linear algebra IMPORTANT DATES Submission Deadline: May 1, 2015 Notification of Acceptance: June 1 Papers Ready: June 15 Tutorials: July 13-14 Workshop: July 15-17 SUBMISSIONS Prospective speakers are invited to submit a contribution to the workshop. - *Short contributions* consist of a 3 page description of the work, and a link to a paper published elsewhere. - Longer *original contributions* consist of a 5-12 page extended abstract which provides sufficient evidence of results of genuine interest and provides sufficient detail to allow the program committee to assess the merits of the work. Submissions of works in progress are encouraged but must be more substantial than a research proposal. Extended versions of accepted original research contributions will be published in Electronic Proceedings in Theoretical Computer Science (EPTCS) after the workshop. Submissions should be prepared using LaTeX, and must be submitted in PDF format. Use of the EPTCS style is encouraged. Submission is done via EasyChair: https://www.easychair.org/conferences/?conf=qpl2015 There will be an award for the best paper whose authors are all students, at the discretion of the programme committee. REGISTRATION Please visit the website to register. We encourage participation by graduate students, and will be able to provide limited reimbursement to partially support students for travel and accommodation. Further information is found on the workshop website.
