The field of gravitational quantum physics brings together ideas from quantum information, metrology, and gravitational physics to address questions such as how gravity affects quantum states, whether quantum properties of gravity can be tested in the weak field regime far below the Planck energy scale, how relativistic concepts extend to quantum systems, and how these effects can be tested experimentally. Many of these questions can now be explored with near-term laboratory experiments and with emerging space-based platforms. The workshop aims to provide a forum for exchange between theorists and experimentalists working on these topics. It focuses on recent results, open theoretical issues, and realistic experimental proposals, and seeks to strengthen coordination within the European research community active in gravitational quantum physics.
Topics covered by the workshop include:
– Tests of quantum aspects of gravity in the weak-field regime
– Quantum metrology for gravitational and relativistic effects
– Gravity-induced entanglement, collapse models, and gravitational decoherence
– Effects of gravity, acceleration, and rotation on quantum states and resources
– Weak-field quantum-gravity effects accessible to near-future experiments
– Equivalence principle and relativistic concepts for quantum systems
– Space-based quantum experiments and quantum technologies in space
The workshop is the main event for the year 2026 of WG2, on “Gravitational Quantum Physics and Metrology”, in the COST Action CA23115 – Relativistic Quantum Information (RQI).
Applications for participation can be submitted until 15th of April via the website https://rqi.fmf.uni-lj.si/apply
