The workshop FAU²: Quantum Gravity Meets Quantum Information – Foundations, Frameworks and Frontiers” focuses on the rapidly developing interface between quantum gravity, quantum foundations, and quantum information theory. Recent advances have shown that concepts such as quantum reference frames, entanglement and geometry, quantum thermodynamics in gravitational settings, measurement and observers in diffeomorphism-invariant systems, black hole information, and open quantum systems offer new insights into the structure of spacetime and the formulation of gravitational dynamics. At the same time, gravitational physics poses profound foundational challenges to quantum theory, particularly regarding time, subsystems, and the role of information.
The workshop brings together researchers from these areas to exchange perspectives, establish a shared conceptual framework, and discuss both foundational and technical developments. Topics will include quantum gravity theories and relation with information and philosophy, holography, relational approaches, decoherence, quantum clocks, and information-theoretic aspects of emergent geometry. By promoting focused interdisciplinary dialogue and identifying common research directions, the meeting aims to clarify open questions and initiate new collaborations.
