EP 105 — Delta.g's Tony Lowe on Taking Quantum Gravity Sensing From Lab to Field

DIB Innovators · Jun 25, 2026 · 50m

Delta.g built a quantum gravity gradiometer that detects underground voids, tunnels, and buried targets in 200 milliseconds per reading, a capability conventional gravity sensors cannot match. Legacy tools are so sensitive to environmental noise that they require extended settling time to separate signal from background, and even then the gravitational reading can be indistinguishable from interference. Delta.g's solution is gradiometry: two stacked identical quantum gravimeters, both built on rubidium atoms cooled to as cold as space, registering the same environmental noise simultaneously…
