Gravity's Ground Truth: The Quantum Sensor That Can See a Pipe Without X-Ray Eyes

Atom interferometry is turning gravity into a surveying tool, with UK trials hunting leaks, voids and buried archaeology without a spade in sight. Here is how quantum gravity sensors work — and where the X-ray vision claims need a hard hat.

The Compass With a Cold: Britain's Satellite-Free Navigation Trials and the Salt-Shaker Rule

Britain is testing quantum accelerometers and magnetometers for navigation when satellite signals fail, from Royal Navy trials to cargo ships and underground mapping. Here is how the sensing works, what has actually been demonstrated, and why 'GPS-free' needs a very large pinch of salt.
