The Army Research Laboratory has demonstrated a compact, Rydberg atom-based quantum sensor capable of measuring the full 3D direction and polarization of radio-frequency fields with approximately two-degree accuracy. This advancement overcomes conventional antenna limitations regarding wavelength and bandwidth, offering significant potential for enhanced spectrum awareness and secure communications in complex electromagnetic environments. While currently focused on military applications, the technology's ability to operate across a broad frequency range in a single package represents a notable step forward in quantum sensing hardware.

Quantum Sensor Advance Could Transform Army Battlefield Signal Detection

The Quantum InsiderJune 9, 20264 min read

Insider Brief PRESS RELEASE — Army scientists achieved a major milestone in quantum sensing technology that could transform how electromagnetic signals are detected on the battlefield. For the first time, scientists at the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory demonstrated a quantum sensor that can measure the full 3D direction of radio-frequency electromagnetic fields. This breakthrough could provide the Army with tools to improve situational awareness, enhance secure communications and enable […]

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…
