Description
We describe progress toward quantum enhancement of an optically pumped magnetometer (OPM), operating around Earth's magnetic field. We demonstrate back-action evading scheme with sub-pT/vHz quantum-noise-limited sensitivity, for frequency and amplitude modulation schemes. We also aim to demonstrate the quantum advantage of spin squeezing in highly polarized atomic ensembles within microfabricated isotopically enriched 87Rb cells. This work represents a step forward in developing compact and highly sensitive magnetometers, with potential applications in fundamental physics experiments and field-deployable precision sensing technologies.
