Abstract

Abstract: The recent redefinition of the SI bolsters the push towards quantum-based sensors. Rydberg atoms provide a natural link between atomic quantities and electromagnetic fields, where direct absolute measurements can be challenging. We review recent demonstrations of SI-traceable electric field metrology for both high frequency and static fields, communications reception, and angle-of-arrival detection using Rydberg atom spectroscopy.
