"Parameters such as size, drift, and environmental interference often constrain classical sensors. Quantum sensors by contrast can measure fields with precision down to one millionth of Earth’s magnetic signal, enabling the detection of magnetic signals over longer ranges and in environments where signals are weak or noisy. Additionally, the stability of quantum reference states enables drift-free measurements, circumventing the need for constant recalibration and ensuring that users can compare data sets with high reliability. And quantum sensors optimize size, weight, and power parameters. Miniaturized designs make them ideal for deployment on small autonomous platforms such as drones, or in restricted spaces such as inside medical equipment or in underground sensors." ~ https://www.photonics.com/Arti...
