(Sifted.edu) Lockheed Martin, the US defense contractor and Europe’s Element Six, the synthetic diamond-producing arm of diamond company De Beers, are working on a quantum-based navigation technology that would be perfect for covert operations because it is untrackable.
They have created a prototype device — a quantum magnetometer about the size of a large shoebox — that uses synthetic diamonds engineered to have quantum properties to measure the direction and strength of tiny, almost imperceptible anomalies in the Earth’s magnetic field. Combine this with a magnetic field map and you can pinpoint your location on the planet down to the closest — in theory — 50 metres or so.
It can work in conditions where GPS cannot — underwater and underground, for example. Or when you need to ensure you aren’t tracked or want to make sure your navigation devices aren’t being jammed or interfered with.
