Unambiguous measurement in an unshielded microscale magnetometer with sensitivity below 1 pT/rHz
Hamish A. M. Taylor, Christopher C. Bounds, Alex Tritt +1
Cold atom magnetometers exploit a dense ensemble of quanta with long coherence times to realise leading sensitivity on the micrometer scale. Configured as a Ramsey interferometer,…
