On-resonance Rydberg atom--based radio-frequency- (rf) electric-field sensing methods remain limited by the narrow frequency-signal detection bands available from resonant transitions. An additional rf tuner field can be used to dress or shift a target state return detuned signal resonance and thus dramatically extend frequency range for sensing. Here we investigate three distinct tuning-level schemes based on adjacent transitions, which are shown have characteristics controlled with...
We demonstrate resonant detection of rf electric fields from 240 MHz to 900 (very-high-frequency (VHF) ultra-high-frequency (UHF)) using electromagnetically induced transparency measure orbital angular momentum $L=3\rightarrow L'=4$ Rydberg transitions. These states are accessible with three-photon infrared optical excitation. By resonantly detecting in the electrically small regime, these enable a new class atomic receivers. find good agreement between measured spectra and predictions...
We investigate the effects of spatially non-uniform radio-frequency electric (E) field amplitudes on spectral line shapes electromagnetically induced transparency (EIT) signals in Rydberg atomic systems used electrometry (i.e., metrology E-field strengths). Spatially fields distort EIT spectra from that an ideal case, and understanding this distortion is important development atom-based sensors, as these distortions can limit accuracy sensitivity. To characterize distortion, we present a...
Rydberg atom receivers have the potential to supplement or replace traditional sensing technologies due theoretically high sensitivity, electrically small packaging, and unconventional field detection mechanisms they can provide. Given importance of angle arrival (AoA) estimation for geolocation impact these technologies, more work is needed understand sensor’s on AoA estimation. While there been many experimental theoretical efforts improve sensitivity bandwidth quantum sensors, few papers...
