Rydberg Electric Field Sensor Application Spaces

Rydberg atom electric field sensors are projected to enable novel capabilities for resilient communications and spectrum situational awareness. This quantum sensor is small-size, highly sensitive, and broadly tunable, and it has the potential for performing precision angle-of-arrival measurements. While these atomic electric field sensors will not replace traditional receivers in commodity applications for RF signal reception, these sensors could be an enabling technology in niche application spaces. We will discuss the capabilities and limitations of Rydberg atom electric field sensors in the context of resilient communications and other application areas where we see a good match between the two. We will also discuss design considerations with creating a deployable sensor.
