Quantum Sensing, Communications & Security

Quantum sensing uses quantum effects to measure time, motion, gravity and magnetic fields with extraordinary precision, and unlike quantum computing, it can deliver real value without waiting for large, error-corrected machines. The articles in this section follow its steady move from the laboratory into the field, covering more resilient navigation and timing, the supply chains and government demand shaping early adoption, and the practical tests of size, cost and durability that decide which sensors succeed.
