2024: Global Quantum Sensor Market Size Exceeded $377 Million for the Year

In 2024, the global quantum sensor market reached $377.3 million. About a third of this amount fell on the North American region. The industry is showing steady positive momentum, as outlined in the Fortune Business Insights survey, which TAdviser reviewed in mid-December 2025.

Quantum sensors are ultra-sensitive devices that use the principles of quantum mechanics (superposition, entanglement) to measure different physical quantities with the highest accuracy. Such sensors can be used to determine temperature, gravity, magnetic fields, etc. At the same time, they are able to function without direct contact with the object. Quantum sensors are in demand in many areas, including medical imaging and diagnostics, navigation, environmental monitoring, defense and security, and basic research.

One of the market drivers, the authors of the study call the growing demand for quantum sensors in the medical field. These sensors can measure temperature, magnetic fields and electrical signals inside individual cells, allowing the metabolism and activity of neurons to be studied without damage. High-precision quantum magnetometers record the smallest parameter fluctuations, giving a more accurate view of brain function than using electroencephalography (EEG). Quantum sensors allow neural activity to be mapped in unprecedented detail for early diagnosis of neurodegenerative diseases such as Alzheimer's disease.

Another important area of ​ ​ application of quantum sensors, analysts call the defense sector. Such sensors are capable of recording changes in magnetic fields, gravitational forces, and other environmental parameters, providing critical data for positioning, observation, and target detection. Quantum accelerometers and gyroscopes provide high-precision inertial navigation, which is crucial for submarines, aircraft and unmanned vehicles operating in the absence of satellite system signals.

The expansion of the industry is facilitated by artificial intelligence. Neural networks help model and optimize quantum sensor designs, resulting in more efficient, sensitive, and compact devices. Quantum sensors generate huge amounts of data: AI algorithms are able to process and analyze this information at high speed, providing results in real time.

By application, the market is segmented into the automotive industry, healthcare and life sciences, military and defense, agriculture, etc. In 2024, the largest share of revenue was provided by the first of the listed areas, followed by the health sector. Geographically, North America leads with 33.5%, or $126.4 million. Major industry players globally are:

• Campbell Scientific;
• AOSense;
• Apogee Instruments;
• SandboxAQ;
• M Squared Lasers Limited;
• ID Quantique;
• Q-Ctrl;
• LI-Cor;
• Muquans SAS;
• Atomionics;
• SBQuantum;
• Oxford Instruments;
• Nomad Atomics.

In 2025, the quantum sensor market size is expected to reach approximately $435 million. Fortune Business Insights analysts believe that in the future, the CAGR will be 15.8%. Thus, by 2032, expenses may increase to $1.21 billion.^[1]
