The demo took place at the recent U.S. Army Combat Capabilities Development inCommand (DEVCOM) C5ISR Center Network Modernization Experiment 2023 (NetModX23) event.

The Rydberg atomic receiver device worked across the high-frequency (HF) to super high-frequency (SHF) bands and demonstrated over-the-air atomic RF communication at long range.

Other aspects of the company’s sensing technology showcased were signal selectivity, low detection probability and immunity to unwanted interference in contested electromagnetic environments.

When compared to traditional antennas, Rydberg atomic receivers offer a unique set of characteristics, including high sensitivity, selectivity and wideband coverage using a single atomic detector element. Rydberg atom devices have the potential to revolutionize RF surveillance, safety, communications and networking capabilities from long-wavelength RF to millimeter-wave and THz bands.

The Rydberg Atomic Receiver was developed with support from the National Security Innovation Capital (NSIC) funding initiative, a part of the Defense Innovation Unit.
