Quantum Group

We exploreGroup photo the structural connections between physics and computer science, with applications in quantum information and computation, and also in the foundations of physics. We rely in particular on category theory and logic. An international community is forming, with our group playing a leading role. A main activity within the group is the development of categorical quantum mechanics, which was pioneered by Samson Abramsky and Bob Coecke, an activity which ranges from foundations of physics to software development. There is also activity on pure category theory, dynamic epistemic logic, and Quantomatic Development and the Compositional Distributional Model for natural language processing pioneered by Bob Coecke and Mehrnoosh Sadrzadeh.

Joining the group

If you'd like more information about joining the group, please send an email to Samson Abramsky or Bob Coecke. We have supported postdoctoral fellowship applications for strong applicants. The Engineering and Physical Sciences Research Council and the Royal Society have annual fellowship competitions, some of which are open to non-British nationals.

If you're interested in doing a DPhil with us, contact Samson Abramsky, Jonathan Barrett or Bob Coecke. The department now awards scholarships each year to the strongest EU (DTA) and overseas (Clarendon) applicants.

If you're already doing a Masters degree in Oxford and might be interested in doing your project with a member of our group, please get in touch as soon as possible, either with Samson Abramsky, Jonathan Barrett, Bob Coecke, Chris HeunenJamie Vicary, or Aleks Kissinger for categorical quantum mechanics, quantum foundations/information, category theory or computer science logic, and Bob Coecke for computational linguistics, dynamic epistemic logic, or automation.  

If you're an undergraduate and would like to learn more about the sorts of things we work on, have a look at the MSc in Mathematics and the Foundations of Computer Science.

Mailing lists

We run an international quantum foundations mailing list. To subscribe, send a blank email to We also have a separate list to announce local events related to our group's activities; you can subscribe to this by emailing the maintainer.
