Quantum sensors use the sensitivity of quantum states to measure time, magnetic fields, gravity, acceleration and rotation with high precision. Atomic clocks already underpin navigation and networks; newer sensors could support navigation without satellites, medical imaging and underground mapping. This page sets out how quantum sensing works, how mature each application is, and what evidence serves the agencies and industries considering it.

Quantum sensing: how the risk develops.
Measurement, navigation and Earth-science applications. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Atoms keep precise time
Atomic clocks use transitions between atomic energy levels as frequency references. They underpin satellite navigation, telecommunications and financial timestamps.
Interference measures motion and gravity
Atom interferometers split and recombine matter waves to measure acceleration, rotation and gravity, with potential for navigation and subsurface mapping.
Defects sense magnetic fields
Defects in diamond and other sistem sense tiny magnetic fields at small scales, with uses in materials science and biology.
Field use is hard
Laboratory sensitivity often degrades in the field because of vibration, temperature and size constraints. Ruggedising sensors is a major engineering challenge.

Apa yang ditanyakan pakar.
Sensing questions concern precision, robustness and use outside the laboratory.
- How much better than classical instruments is a quantum sensor in real operating conditions?
- Can it be made small, robust and affordable enough for field use?
- Could quantum inertial sensors and clocks provide navigation when satellite signals are lost or jammed?
- What could quantum gravimeters and magnetometers reveal about groundwater, geology and infrastructure?
- What are the dual-use implications, for example for detecting submarines or underground structures?
Mekanisme dan pendorong.
Quantum sensors exploit the fact that quantum states are disturbed by tiny changes in their environment. Atomic clocks measure time by the frequency of atomic transitions. Atom interferometers split and recombine clouds of cold atoms to measure acceleration and gravity. Defects in diamond and other materials act as nanoscale magnetometers. The same sensitivity that gives precision also makes sensors vulnerable to noise, vibration and temperature changes.
The step from laboratory to field is the main challenge. Many quantum sensors require lasers, vacuum sistem and careful isolation. Engineering progress is reducing size and power, but performance in a moving vehicle or harsh environment is often well below laboratory results.
