From 20-22 August 2025, the third Terrestrial Very Long Baseline Atom Interferometry (TVLBAI) Workshop took place in Hanover, bringing together about 100 researchers from around the world.
The workshop aimed to discuss the technological and physical foundations for large-scale atom interferometry projects and to develop a comprehensive roadmap for their implementation. The workshop strengthened networking among researchers and institutions by fostering strategic discussions and paving the way for future funding. Emphasis was placed on collaboration among the fields of cold atoms, astrophysics, cosmology, and fundamental physics.
With the goal of realizing at least one km-scale detector by 2035, which would systematically explore the mid-frequency band of gravitational waves and probe possible ultralight dark matter, the TVLBAI Workshop is a crucial step towards the next generation of atom interferometry experiments.
Besides the discussions the visit to the newly established and now operational 10m VLBAI facility was another highlight, along with tours of the laboratories at the Institute of Quantum Optics and the Einstein Elevator in Hanover. These facilities offer unique opportunities for research in the field of atom interferometry.
