Quantum’s Quietest Branch: A Case for Magnetometry

But dismissing the heartbeat tale should not mean dismissing quantum magnetometry.

Demystifying Quantum Magnetometry Most people have cursory knowledge about magnetometry, which measures the strength and sometimes the direction of magnetic fields generated by electric currents and magnetized materials.

A magnetic field makes the aligned spins wobble, darkening the glass cell by the exact amount that field deflects them.

Operationalizing Quantum Magnetometry Quantum magnetometry reveals metal and movement from a distance and without emitting a signal that adversaries can detect much less dodge or jam.

Prescriptions Although physics binds performance on issues like clutter and noise filtering, the key barriers to fielding quantum magnetometry lie in procurement and assimilation.
