MHz to sub-kHz field detection with an all-dielectric potassium Rydberg-atom sensor
Daniel Hammerland, Rajavardhan Talashila, Dixith Manchaiah +8
Rydberg sensors have significant promise as an alternative to the antenna systems used for sub-MHz frequency communications, where the scale of high-efficiency antennas is often im…
Fundamental linewidth limit of electromagnetically induced transparency in a thermal Rydberg ladder
Noah Schlossberger, Nikunjkumar Prajapati, Alexandra B. Artusio-Glimpse +2
Spectroscopy of Rydberg states has become a popular platform for quantum sensing, with the most common readout scheme being two-photon electromagnetically induced transparency (EIT…
Simultaneous Detection, Demodulation, and Angle-of-Arrival Determination of Communication Signals Using a Dual Ladder Rydberg Receiver
Stone B. Oliver, Samuel Berweger, Eugeniy E. Mikhailov +4
In a typical Rydberg mixer, modulated communication signals are detected using a radio frequency (RF) heterodyne technique. The mixer outputs an intermediate frequency (IF), which…
Sensitivity Comparison of Rydberg Atom-Based Radio-Frequency Electric Field Detection: Ionization Current Versus Optical Readout
Dangka Shylla, Rajavardhan Talashila, Alexandra Artusio-Glimpse +7
We investigate a technique for detecting radio-frequency (RF) electric fields in a Cesium (Cs) vapor cell at room temperature by collecting charge from ionized Rydberg atoms and co…
An Imaging Radar Using a Rydberg Atom Receiver
William J. Watterson, Nikunjkumar Prajapati, Rodrigo Castillo-Garza +5
Rydberg atoms in a gas form are highly sensitive electric field probes capable of detecting and measuring the amplitude, phase, and polarization of broadband time-varying signals.…
Imaging of induced surface charge distribution effects in glass vapor cells used for Rydberg atom-based sensors
Link Patrick, Noah Schlossberger, Daniel F. Hammerland +6
We demonstrate the imaging of localized surface electric (E) field effects on the atomic spectrum in a vapor cell used in Rydberg atom-based sensors. These surface E-fields can res…
