QPL 2023

The 20th International Conference on Quantum Physics and Logic (QPL 2023) will take place from 17 July to 21 July 2023 at Institut Henri Poincaré in Paris, France. Quantum Physics and Logic is an annual conference that brings together academic and industry researchers working on mathematical foundations of quantum computation, quantum physics, and related areas. The main focus is on the use of algebraic and categorical structures, formal languages, type systems, semantic methods, as well as other mathematical and computer scientific techniques applicable to the study of physical systems, physical processes, and their composition. Work applying quantum-inspired techniques and structures to other fields (such as linguistics, artificial intelligence, and causality) is also welcome.

Important Dates

All deadlines are stated with respect to the Anywhere on Earth (AoE) time zone.


Prospective speakers are invited to submit one (or more) of the following:

Page limits exclude bibliography and appendices (which may be read at the discretion of reviewers). All submissions will be handled by EasyChair.

There will be an award for Best Student Paper that will be determined by the Program Committee. Papers eligible for the award are those where all the authors are students at the time of submission.


Registration is now open. More information is available here.


Authors of accepted proceedings and non-proceedings submissions will be invited to give a talk. Authors of accepted poster submissions will be invited to present their work at the poster session. Authors of accepted programming tool submissions will be invited to live demo their tool to conference attendees.

The conference program is available here.

Conference Proceedings

Conference proceedings will be published in Electronic Proceedings in Theoretical Computer Science (EPTCS) after the conference. When preparing the final version for publication, authors of accepted proceedings submissions are allowed to use up to three extra pages (i.e. up to 15 pages excluding bibliography) to address reviewer concerns and suggestions under the provisio that they do not introduce new results.

Local Information

The conference will take place at Institut Henri Poincaré in Paris, France.

Paris has a dense public transportation network: metro, bus, tram and RER (regional train). A single one-way ticket costs 2.10€. There also are packs and day passes. Notice that RER outside Paris (e.g. from/to airports) has specific fares. See also local travel advice from IHP.

The two amphitheaters, Hermite and Darboux, are located on the ground floor. Coffee breaks will be held in between the morning sessions, and in between the afternoon sessions, in the space next to the two amphitheaters. Please do not eat or drink anything (except water) inside the amphitheaters. An additional room on the ground floor is at our disposal.

We are also given access to the library on the first floor of the building. The only requirement is to simply fill in the registration list at the entrance of the library. The library is quite nice and it is worth checking out!

Eduroam is accessible on site.

Alternatively, you may use the “IHP-Guest” network, which can be accessed using the following procedure:

  1. Select the “IHP-Guest” network.
  2. In the pop-up window, click on the button “Receive your credentials on this portal”.
  3. Fill in the form, and click “Register”.
  4. You get your credentials for the current day.
  5. Clicking “Back”, you get to the registration portal, but the credentials should be filled in. Click on “Connect”. You now have access to the internet.

The conference dinner will take place at “Les Belles Plantes” located at 47 Rue Cuvier. It is a short walk (approximately 15 minutes) from the conference venue. The dinner will be vegetarian with vegan options available upon request.

Lunches are not provided by the conference organisers. There are many restaurants and food options close to the conference venue.
