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…
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…
Probing Bandwidth and Sensitivity in Rydberg Atom Sensing via Optical Homodyne and RF Heterodyne Detection
Dixith Manchaiah, Stone Oliver, Samuel Berweger +2
Rydberg atom based sensors allow for SI traceable measurements and show promise for applications in the field of communication and radar technologies. In this article, we investiga…
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…
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…
