Workshop Scope:

The 4th Terrestrial Very-Large-Baseline Atom Interferometry (TVLBAI) Workshop in Canfranc (Spain) follows the three successful editions held previously in Geneva (March 2023), London (April 2024) and Hannover (August 2025).

This workshop will gather international experts from several scientific and technological areas of relevance to TVLBAI, with the primary objective of progressing towards the realisation of kilometre-scale experiments planned to become operational in the mid-2030s.

Besides reviewing the scientific and technological advancements in the field since the previous meetings, this workshop will also dedicate time to discuss the activities of the various Work Packages of the TVLBAI Proto-Collaboration.

The workshop will be hosted at Canfranc underground laboratory (Laboratorio Subterraneo de Canfranc, LSC), which offers exceptional low-noise conditions for fundamental physics experiments. Participants will have the opportunity to visit this facility and its experiments.

In the same spirit as in the previous editions, this workshop intends to strengthen the sense of community among participants and will help to consolidate the international network of experts and enthusiasts in atom interferometry for fundamental physics.
