Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms
Noah Schlossberger, Andrew P. Rotunno, Stephen P. Eckel +14
Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently…
Observation of Asymmetric Sideband Generation in Strongly-driven Rydberg Atoms
Dangka Shylla, Nikunjkumar Prajapati, Andrew P. Rotunno +7
Improving the bandwidth of Rydberg atom-based receivers is an ongoing challenge owing to the long-lived Rydberg state lifetimes that limit the refresh rate of ground state atoms. I…
Increased instantaneous bandwidth of Rydberg atom electrometry with an optical frequency comb probe
Alexandra B. Artusio-Glimpse, David A. Long, Sean M. Bresler +8
We show that the use of an optical frequency comb probe leads to dramatically improved bandwidth (as high as 12+/-1 MHz) for the detection of modulated radio frequencies in Rydberg…
Independent Rydberg Atom Sensing using a Dual-Ladder Scheme
Samuel Berweger, Alexandra B. Artusio-Glimpse, Nikunjkumar Prajapati +6
Rydberg atom-based electric field sensing can provide all-optical readout of radio frequency fields in a dielectric environment. However, because a single set of optical fields is…
Zeeman-resolved Autler-Townes splitting in Rydberg atoms with tunable resonances and a single transition dipole moment
Noah Schlossberger, Andrew P. Rotunno, Aly Artusio-Glimpse +5
Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In this paper we provide a theore…
High angular momentum coupling for enhanced Rydberg-atom sensing in the VHF band
Nikunjkumar Prajapati, Jakob W. Kunzler, Alexandra B. Artusio-Glimpse +7
Recent advances in Rydberg atom electrometry detail promising applications in radio frequency (RF) communications. Presently, most applications use carrier frequencies greater than…
EIT spectra of Rydberg atoms dressed with dual-tone radio-frequency fields
Maitreyi Jayaseelan, Andrew P. Rotunno, Nikunjkumar Prajapati +4
We examine spectral signatures of Rydberg atoms driven with near-resonant dual-tone radio-frequency (RF) fields in the regime of strong driving. We experimentally demonstrate and t…
Inverse Transform Sampling for Efficient Doppler-Averaged Spectroscopy Simulations
Andrew P. Rotunno, Amy K. Robinson, Nikunjkumar Prajapati +4
We present a thermal velocity sampling method for calculating Doppler-broadened atomic spectra, which more efficiently reaches a smooth limit than regular velocity weighted samplin…
Detection of HF and VHF Fields through Floquet Sideband Gaps by `Rabi Matching' Dressed Rydberg Atoms
Andrew P. Rotunno, Samuel Berweger, Nikunjkumar Prajapati +6
Radio frequencies in the HF and VHF (3 MHz to 300 MHz) bands are challenging for Rydberg atom-based detection schemes, as resonant detection requires exciting the atoms to extremel…
Phase-Resolved Rydberg Atom Field Sensing using Quantum Interferometry
Samuel Berweger, Alexandra B. Artusio-Glimpse, Andrew P. Rotunno +5
Although Rydberg atom-based electric field sensing provides key advantages over traditional antenna-based detection, it remains limited by the need for a local oscillator (LO) for…
Sensitivity Comparison of Two-photon vs Three-photon Rydberg Electrometry
Nikunjkumar Prajapati, Narayan Bhusal, Andrew P. Rotunno +7
We investigate the sensitivity of three-photon EIT in Rydberg atoms to radio frequency detection and compare it against conventional two-photon systems. Specifically, we model the…
Rydberg state engineering: A comparison of tuning schemes for continuous frequency sensing
Samuel Berweger, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +11
On-resonance Rydberg atom-based radio-frequency (RF) electric field sensing methods remain limited by the narrow frequency signal detection bands available by resonant transitions.…

Andrew P. Rotunno, Amy K. Robinson, Samuel Berweger +4
We present a model for calculating broadened Autler-Townes spectra when probing ac electric field magnitudes by use of Rydberg atom electromagnetically-induced transparency. This m…
