Quantum Sensors: A Revolution in Measurement Detection

Published by Olivier Tonneau | N° 210 - Quantum, microelectronics, conquering the nanometer and beyond

In the field of technology and science, quantum sensors are emerging as a major innovation, opening up unprecedented perspectives in the detection of physical signals, and consequently the gathering of new information about the world. Based on the principles of quantum mechanics, these sensors push back the limits of sensitivity and precision, offering considerable advantages over conventional sensors in a wide range of applications, from measuring magnetic fields to detecting weak forces and much more. These promising prospects are attracting funding, so much so that the quantum sensor market could reach a size of three billion dollars by 2030.


How Quantum Sensors work Quantum sensors exploit the properties of quantum physics to take measurements with far greater sensitivity and accuracy than conventional sensors. A typical example of a quantum sensor are NV centers. NV centers, or nitrogen vacancy centers (vacancies generated in the matrix of synthetic diamonds), create an electronic "spin", sensitive to magnetic and electric fields and to variations in their local environment. They can therefore be used as high-precision sensors to...
