QED-C：2026年量子传感与国家安全：航天和国防领域应用评估报告（英文版）

Precision measurement is essential to many U.S. space and defense missions, including GPS-denied navigation, missile defense, explosive device detection, satellite positioning, electronic warfare, and secure communications. Quantum sensors, which use quantum systems such as atoms, photons, and electron or nuclear spins to make highly precise measurements, already support several of these missions; atomic clocks, for example, are essential to GPS. With focused investment and realistic assessme
