As a key application area of quantum sensing, geomagnetic quantum magnetometers are experiencing rapid growth, driven by the following major trends:

Performance breakthroughs:
Pushing beyond sensitivity limits to achieve femtotesla (fT) level accuracy and even higher, while significantly improving long-term stability.

Expanded applications:
Extending beyond traditional mineral exploration into high-value fields such as biomagnetic sensing (e.g., magnetocardiography and magnetoencephalography), industrial non-destructive testing, and urban underground space monitoring.

Commercialization:
With advances in micro- and nano-fabrication technologies, systems are evolving toward miniaturization, low power consumption, and cost efficiency, accelerating the transition from laboratory research to large-scale deployment.

Technology convergence:
Integrating quantum sensing with quantum computing, communication technologies, and AI-driven algorithms to enable next-generation intelligent sensing networks.
