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.…
Determining angle of arrival of radio frequency fields using subwavelength, amplitude-only measurements of standing waves in a Rydberg atom sensor
Rajavardhan Talashila, William J. Watterson, Benjamin L. Moser +6
Deep subwavelength RF imaging with atomic Rydberg sensors has overcome fundamental limitations of traditional antennas and enabled ultra-wideband detection of omni-directional time…
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…
