Quantum magnetometry applications
Magnetic signals are mapped into precession phase or resonance frequency.
$$\delta B\approx\delta\phi/(\gamma T)$$
Physical intuition
Magnetic signals are mapped into precession phase or resonance frequency.
Deep dive: physical mechanism
Match platform, bandwidth and spatial resolution to the source, from biomagnetic fields to materials characterization.
What is measured experimentally?
Field maps, spectral lines and sensitivity curves establish performance.
Assumptions, noise and limitations
Shielding, sensor–sample distance and cross-sensitivity matter.
