Ultra-precise quantum sensors could be built, help in GPS-denied platforms like submarines

Scientists have developed a breakthrough method to work around the Heisenberg uncertainty principle by "squeezing" quantum uncertainty away from important measurements. Using trapped ion vibrations and "grid states," researchers achieved unprecedented precision in detecting tiny changes in both a particle's position and momentum simultaneously, surpassing classical sensors. This advancement could enable ultra-precise quantum sensors for navigation in GPS-denied environments like submarines, underground areas, and space, while improving medical imaging and fundamental physics research.
