Rilevamento quantistico

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.

02La domanda

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.

Meccanismo

Atoms keep precise time

Atomic clocks use transitions between atomic energy levels as frequency references. They underpin satellite navigation, telecommunications and financial timestamps.

Meccanismo

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.

Meccanismo

Defects sense magnetic fields

Defects in diamond and other sistemi sense tiny magnetic fields at small scales, with uses in materials science and biology.

Meccanismo

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.

09Questioni centrali

Cosa si chiedono gli esperti.

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?
10Meccanismi

Meccanismi e fattori.

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 sistemi 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.

14Domande

Domande e risposte.

What is a quantum sensor?
A device that uses quantum states, such as atomic energy levels or superposition, to measure physical quantities with high precision.
Are atomic clocks quantum technology?
Yes. They use quantum transitions in atoms and have been in use for decades, underpinning satellite navigation and network timing.
Can quantum sensors replace GPS?
Quantum inertial sensors and clocks could support navigation when satellite signals are unavailable, but field systems are still being developed and tested.
Is quantum sensing already in use?
Yes, in some forms. Atomic clocks are long established. Newer sensors such as quantum gravimeters and magnetometers are in research, trials and early commercial use.
Could quantum sensors replace satellite navigation?
Not entirely. Quantum inertial sensors could reduce drift when satellite signals are unavailable, but they measure motion relative to a starting point and still accumulate some error over time.
Why is sensing considered dual use?
Because the same precision that helps map groundwater could detect hidden objects or structures. That raises questions of export control and responsible use.
