Quantum states are extraordinarily sensitive to environmental changes. Quantum sensors use this sensitivity to outperform their classical counterparts. We have the opportunity to extend the applications of quantum sensors by integrating entanglement into their operation to increase sensitivities and provide selectivity.
There is a rich opportunity for new sensors where quantum processes lead to improved performance, and even to simpler and less expensive sensors. For example, TQT research teams are targeting quantum sensors that can report on specific parameters such as in vivo glucose in tissue separate from blood; chemically specific low concentration metabolites to enable personalized medicine; interferometers with superior signal-to-noise performance; and miniaturized magnetometers to detect magnetic anomalies for defense applications.
