Quantum Gravity (QG) is a florishing and facinating area of research. Although elaborating a full theory of QG is challenging, phenomenology of QG has florished in the last two decades. QG phenomenology involves both theorists and experimentalists in a wide variety of fields (particle physics, cosmology, astroparticles, ...), some related to the most fundamental theories, while others focus on analyzing data collected by performant expriments in astroparticle physics (neutrinos, gravitational waves, X-rays, gamma-rays...), particle physics, or table top experiments.
The international conference "Bridging high and low energies in search of quantum gravity 2025" (BridgeQG 2025) is the first annual conference of COST Action CA23130.
Its goal is to favor exchanges between the various communities eager to tackle the challenges of QG phenomenology. After introductory talks on the most recent developments on theories and experiments in the fields of high-energy and low-energy QG phenomenology, the conference will be open to contributions. Invited speakers will develop some hot topics relevent to the field.
The conference will be held in Paris, France from 7 to 10 July 2025. It is fully funded by COST Association through COST Action CA23130. No registration fee is required.
Registration
This conference is meant to favour in-person interactions and effective networking. As a result, even though online participation is possible, the OC decided online participants will not be allowed to give a talk. Online participants will have to register using the dedicated registration form.

The COST Action CA23130 BridgeQG
Recent advances in both high-energy astrophysics and high-precision table-top experiments are pushing our capability to test nature in regimes where gravity meets quantum physics. Astrophysical observations are now potentially sensitive to tiny residual effects of Planck-scale physics, while table-top experiments are reaching the precision needed to test the interplay between gravity and quantum systems at ultra-low energies. Investigations of these regimes, in particular once they are combined, will provide important clues towards the understanding of the full-fledged theory of quantum gravity.
The main aim of the Action is to bring together scientists with a variety of complementary expertise: theorists working on quantum gravity or the interplay between gravity and quantum physics with quantum information and quantum optics tools, and experimentalists involved in astrophysical searches for quantum gravity, or investigating the effects of gravitational interactions on quantum systems. The resulting interdisciplinary collaboration will develop a common language and a shared framework which will boost investigations at the interface between high-energy quantum gravity and quantum aspects of gravity in the weak-field regime. The Action will also facilitate cross-disciplinary training and exposure of young scientists to different communities with a common goal, serving as a career accelerator. The synergy within this newly-formed community will be essential to systematically search for quantum gravity on all scales, and possibly find the first signatures of new physics.
The topics covered by BridgeQG are particularly suited for outreach. The Action will promote interest in fundamental physics among the general public and in particular school pupils.
