Gravimetry is the only geophysical method able to provide direct information on underground mass changes. It is critically important for both resource management (e.g., water, geothermal fluids) and risk assessment (e.g., volcanic activity, floods and droughts, melting of glaciers).
By 2029, EQUIP-G will submit a roadmap and recommendations to the European Commission for the implementation of a future perennial European Quantum Infrastructure for gravimetry.

Our initial use cases are :
Similarly to Newton’s apple experiment, quantum gravimeters use a free-falling cloud of laser-cooled atoms as a test mass. The accelerated free-fall is measured by atom interferometry. This technique exploits the effect of quantum superposition and the matter-wave duality of atoms in the frame of the second quantum revolution .
