The spin and electronic degrees of freedom in atomic systems provide sensitive and versatile means for detecting electromagnetic fields, from DC to THz frequencies, with spatial resolutions ranging from the nanoscale to meter scale. Such sensors offer unique advantages compared to classical approaches, resulting from their intrinsic quantum nature. We review three different sensor modalities: atomic vapor magnetometers, nitrogen-vacancy-center magnetometers, and radio-frequency sensors based on Rydberg atoms. We emphasize the unique features and capabilities of these types of sensors in the context of real-world applications.

Quantum sensors represent a new generation of sensors with improved precision, accuracy, stability, and robustness to environmental effects compared to their classical predecessors. After decades of laboratory development, several types of quantum sensors are now commercially available or are part-way through the commercialization process. This paper provides a brief description of the operation of a selection of quantum sensors that employ the principles of atom–light interactions and discusses progress toward packaging those sensors into products. This paper covers quantum inertial and gravitational sensors, including gyroscopes, accelerometers, gravimeters, and gravity gradiometers that employ atom interferometry, nuclear magnetic resonance gyroscopes, atomic and spin-defect magnetometers, and Rydberg electric field sensors.
