Delta g is a quantum technology and gravity gradiometry company on a mission to make gravity sensing technology as ubiquitous as GPS, radar and telecoms. Spinning out from the University of Birmingham in 2023, our technology is the world’s first quantum technology based gravity gradient capability to successfully detect buried features from their gravity profile alone. Gravity sensors have the potential to impact much of todays world for the better; reducing traffic jams by eliminating unnecessary roadworks, a reliable navigation alternative to GPS and improving the environment through better monitoring and models. Limitations in current technology have prevented gravity sensing from reaching its disruptive potential. Our solution harnesses the quantum nature of atoms to produce a gravity gradient capability that is inherently immune to many of the noise sources hindering current technology. Enabling measurements in previously impossible environments at a fraction of the cost. A world-class team of experts from science, engineering, and business, supported by end-users from civil engineering, infrastructure, defence, and rail, Delta g will realise our vision of creating the Google Maps of the underground.
