QPL 2015

Quantum Physics and Logic

13-17 July 2015
Oxford, United Kingdom

The 12th International Workshop on Quantum Physics and Logic will take place at the Department of Computer Science of the University of Oxford between Wednesday 15 and Friday 17 July, 2015.

QPL is a workshop that 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).

The workshop will be preceded by tutorials on Monday 13 and Tuesday 14 July 2015.

Important dates

  • Submission deadline: 1 May 2015
  • Author notification: 1 June 2015
  • Papers ready: 15 June 2015
  • Tutorials: 13-14 July 2015
  • Workshop: 15-17 July 2015

All deadline times are Anywhere on Earth.

Submit a paper

Prospective speakers are invited to submit a contribution to the workshop. We are considering two kinds of contributions.

  • Short contributions consisting of a 3 page description of the work, and a link to a paper available elsewhere.
  • Longer original contributions consisting 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 after the workshop.

    Submissions should be prepared using LaTeX, and must be submitted in PDF format. Use of the EPTCS style is encouraged. Please submit your contribution via EasyChair.

    There will be an award for the best paper whose authors are all students, at the discretion of the programme committee.



    Monday 13 July and Tuesday 14 July there will be tutorial talks.

    Local information

    Oxford is the home of the oldest university in the English speaking world, and boasts many tourist attractions. It is easily reached from London's international Heathrow airport via the so-called airline bus service. For more information see these travel directions.

    We have reserved a number of rooms in Keble College for participants at the reduced rate of 42 pounds per night. These can only be booked for either 5 or 6 nights, 12-17 or 12-18 July 2015, on a "first come, first serve" basis. A room can be reserved when you register.

    Oxford has a wide range of places to stay, including college accommodation, private rooms and flats, or short term properties to share, and many bed and breakfasts (B&Bs) and guest houses. Particularly well located B&Bs are Cotswolds, Rewley House, Linton Lodge, Parklands and Galaxie Hotel. Please contact Destiny Chen should you need further information. Demand for accommodation in Oxford is high, so the rule of thumb is to book a place as soon as possible. In terms of areas, Central/North Oxford and Jericho are the closest to the workshop venue, then along Botley Road, Abingdon Road, Cowley Road (the multicultural downtown of Oxford), Iffley Road, and Wolvercote.

    The workshop will be held in Lecture Theatre B of the Department of Computer Science.

    Oxford hosts many tourist attractions and events. For example, you could complete your Oxford experience by seeing a Shakespeare play outdoors.
