Ultra-Sensitive Quantum Sensors Deliver Security, Too

Remote sensing—a category broad enough to include both personal medical monitors and space weather forecasting—is poised for a quantum upgrade, much like computing and cryptography before it. A new type of quantum sensor that promises both higher sensitivity and greater security has been proposed and tested in proof-of-concept form. What remains to be seen is how broadly it will be adopted, and whether such quantum enhancements might ultimately …
