A new sensor that can detect the entire radio spectrum could play a big role in the future of electromagnetic warfare and communications.
In January, David Meyer, Paul Kunz, and Kevin Cox with the Army Research Lab published a new paper (https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.15.014053) describing how they used atoms in a quantum state called a Rydberg state to detect electromagnetic emissions up to 20 GHz. That includes the frequencies that carry Bluetooth, WiFi, and other communication methods
Cox said these applications take advantage of a different aspect of quantum science that he called “identicalness.”
