By developing advanced algorithms and methodologies, GReD contributes to improving the accuracy and efficiency of quantum gravity measurements. Their work ensures that the cutting-edge sensors developed within FIQUgS can be effectively integrated into geophysical studies, enabling more precise subsurface mapping and monitoring.On February 9, Martina presented the latest developments of FIQUgS and its applications for geophysics.
On February 7, the FIQUgS project was presented at the Second National Conference of the National Quantum Science and Technology Institute (NQSTI) in Rome (nqsti.it). This event provided a valuable opportunity to highlight the project’s advancements and its role in developing quantum sensors for geophysical applications.The presentation focused on FIQUgS' mission to enhance the accuracy and usability of quantum gravimeters, which have the potential to revolutionize geophysical exploration.
At EQTC2024 in Lisbon, Camille Janvier, PhD from Exail presented the latest results of the FIQUgS project, showcasing the power of quantum gravimetry for archaeological exploration. By measuring both gravitational acceleration and its vertical gradient, the DQG enables high-resolution underground mapping for geoscience and civil engineering. Thanks to Centro de Arqueologia de Lisboa (António Marques), PQI – Portuguese Quantum Institute (Yasser Omar), and GReD for their contributions to this milestone!
Following a 6-month hardware upgrade, the instrument was able to successively improve on its previous performances in terms of stability and sensitivity. It demonstrated a stability on the gradient measurement down to 0.1 Eotvos (0,1 nm/s²/m or 0,01 µGal/m) on two successive 5-days streaks. Sensitivity was also improved by 50%. This is as far as we know the best sensitivity achieved for an industrial quantum differential gravimeter yet.
If you are attending EGU24 this week in Vienna, don't miss Jeremie Richard on Thursday (session G4.2) and a shared poster with Helmholtz-Zentrum Potsdam - Deutsches GeoForschungsZentrum GFZ this afternoon (in session G4.3).
EIC Accelerator is a prestigious EU acceleration program that offers grants to startups and SMEs. The program awarded WIDMO Cities with a significant investment in blended finance to realize our groundbreaking idea of large-scale mapping of the subsurface of cities. This milestone allows WIDMO to revolutionize urban planning and infrastructure development, unlocking the hidden potential beneath our cities. Congrats 👏.
Exail was glad to exhibit its quantu gravimeter and to introduc its quantum sensing activities on the CNRS booth at Viva Technology with the visit of Emmanuel macron, Bruno Le Maire but also Alain Aspect (2022 Physics Nobel Prize) and Antoine Petit (CEO at CNRS). Quantum and Photonics activities of Exail are still benefitting from stronc collaborations with academic labs and several European Research projets such FIQUgS, CARIOQA, QIA...
