Quantum computing is still a while away from widespread commercial application, but another technology could become available much sooner – quantum sensing. Quantum sensors can measure different physical properties, including temperature, magnetic field, and rotation, with extreme sensitivity. These sensitives give the technology distinct advantages for applications including communication, infrastructure monitoring, navigation, and radar. Henry White, Lead Technologist in Sensing at BAE Systems, joins me in a conversation on 'Making Sense of Quantum Sensing'? We discuss what the technology is in more detail, as well as the current and potential real-world applications of quantum sensing, such as threat detection in the military or at airports.
