Rydberg Atom Electric Field Sensor Capabilities in the High Frequency Regime

Rydberg atom electric field sensors are projected to enable novel capabilities for communications and sensing due to their small size, high sensitivity, and broad frequency tunability. Much of the current work has been focused on exploring the sensor's capabilities in the GHz portion of the electromagnetic spectrum; however, their small size and potential to perform high accuracy measurements could provide key advantages in the MHz regime to support high frequency (HF) communications. We will discuss our efforts to characterize near and far term Rydberg sensor performance in the HF band and provide comparisons to traditional antenna-based receiver systems of similar sensor volume.
