Insider Brief
Scientists at the U.S. Army DEVCOM Army Research Laboratory demonstrated the first quantum sensor capable of measuring the full three-dimensional direction, polarization and propagation of radio-frequency electromagnetic fields.
The Rydberg atom-based sensor operates across an exceptionally broad frequency range while remaining only a few centimeters in size, overcoming limitations of conventional antennas that are constrained by signal wavelength and bandwidth.
Researchers reported that the sensor can identify the direction of incoming signals with an accuracy of about two degrees, a capability that could improve spectrum awareness, communications and decision-making in complex battlefield environments.
PRESS RELEASE — Army scientists achieved a major milestone in quantum sensing technology that could transform how electromagnetic signals are detected on the battlefield.
