Underground quantum sensing set to erupt

Susan Curtis explores the new breed of quantum gravimeters finding their way onto the slopes of Mount Etna and into tunnels deep under Birmingham

The DQG is composed of a main sensor head standing at 175cm high, around 66 kg, connected to the ILS system, at around 33kg. The combined system can be operated with a power as little as 200W. Credit: iXblue

iXblue develops commercial quantum sensor for underground mapping

The system can measure simultaneously the absolute values of both gravitational acceleration and its vertical gradient
