Quantum sensors reshape privacy

Beyond computing and cryptography, the second quantum revolution is delivering highly sensitive quantum sensors and clocks that can detect minute changes in gravity, magnetic fields, and time. Those civilian sensors could enable new capabilities — from subterranean imaging to ultra‑precise location services — that change what governments and firms can observe about people and places. — If quantum sensing becomes widespread it will force new debates about surveillance law, infrastructure siting, and privacy protections because observational power, not just computing power, will grow dramatically.
