Quantum Sensing as a Technology
Quantum sensors exploit our ability to control atoms and subatomic particles at will, and even place them within a particular quantum state, which is likewise extremely sensitive to minimal disturbances in the environment. They offer both unique sensitivity and accuracy and are about to revolutionize detection in several fields: Medicine, civil engineering, telecommunications, natural resources management as well as fundamental physics. Application of these sensors covers motion (including acceleration, rotation, and gravity) electric and magnetic fields, and imaging. They can provide very accurate measurements across many frequencies, have no drift, or need to calibrate and rely on advanced quantum techniques, such as squeezing or entanglement to improve sensitivity or precision. Still large in size, complicated, and extremely experimental, these sensors are becoming a major pillar of quantum technologies. This special collection presents recent progress of this technology, shows how the next generations will shrink, integrate, and improve their performance to expand their range of applications.
