We are pleased to announce the 2026 edition of Time in Quantum Theory, which will take place on 25–28 May 2026 at Stockholm University.
The TiQT conference series brings together researchers from theoretical physics, experimental physics, and philosophy to exchange ideas on the nature of time in quantum theory and related areas.
Topics of interest include:
- fundamental limits of timekeeping
- foundational, operational, and experimental approaches to temporal measurement
- relativistic and gravitational effects
- quantum clocks and reference frames
- causality and temporal structure
- thermodynamics and the arrow of time
- philosophical perspectives on time in quantum theory
Confirmed speakers include:
- V. Vilasini (University of Grenoble)
- Eddy Chen (University of California San Diego)
- Lucy James (University of Bonn)
- Joshua Foo (University of Waterloo, from April onwards affiliated with Kyushu University)
We invite the submission of abstracts for contributed talks and posters, by 15 March 2026. Further details, including registration information and updates, will be made available via this website.
The conference is organized under Working Group 3 of the COST Action 23115 on Relativistic Quantum Information (RQI). COST is an EU-funded programme supporting scientific collaboration and training across its member states. Further information about the Action is available at https://rqi-cost.org. Interested participants are also welcome to join the Action as members.
There will also be a linked summer school on "Time, Memory, and Causality in Quantum Physics" the week before (18.–23.5.2026), as part of this COST Action. Especially junior participants are warmly welcomed to register for both events!
