Microfabricated optically-pumped magnetometers (OPMs) are advancing magnetic sensing and imaging for applications in space, defense, geophysics, industrial, and biomedical applications. OPM sensors have been developed in academia and national laboratories over the last 20 years, demonstrating the capabilities of small uncooled magnetometers with performance rivaling those of low-temperature superconductors. Many cross-validation demonstrations enabled the adoption of these novel quantum magnetometers in new applications. Translating this technology into industry poses many new challenges, but also opens the door for faster adoption by putting them into the hands of the users. Two example applications are discussed: microfabricated zero-field OPMs for non-invasive functional brain imaging and microfabricated Mz scalar-vector magnetometers for integration into Cubesats for geomagnetic surveying and monitoring. Both applications pose unique challenges and take advantage of unique features of these quantum sensors.
