The Rydberg spectrum analyzer and other quantum sensors have the potential to unlock a new frontier of Army sensors for spectrum awareness, electronic warfare, sensing, and communications as part of the Army’s modernization strategy. We demonstrate an atom-based amplitude-modulation (AM) receiver for digital communication with a weak continuous frequency carrier using a Rydberg AC Stark. A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army. Officials claim that the Rydberg atoms are sensitive to the circuit’s voltage, enabling the device to be used as a sensitive probe for the wide range of signals in the RF spectrum.Īccording to DEVCOM, the Rydberg spectrum analyzer has the potential to surpass fundamental limitations of traditional electronics in sensitivity, bandwidth, and frequency range.

Army Combat Capabilities Development Command (DEVCOM) have developed a new quantum sensor capable of analyzing the full spectrum of radio frequency (RF) and real-world signals, creating new potential for soldier communications, spectrum awareness, and electronic warfare.Īrmy researchers built the sensor, which can sample the radio-frequency spectrum - from zero frequency up to 20 GHz - and detect AM and FM radio, Bluetooth, Wi-Fi, and other communication signals, according to researchers.Ĭalled the Rydberg sensor, the system uses laser beams to create highly-excited Rydberg atoms directly above a microwave circuit, to boost and hone on the portion of the spectrum being measured. The radio-frequency tests are the last time that the payload of Quantum will be switched on until after its launch.
