Vapor cell Rydberg atom electrometry with time-separated fields

Motivation

Quantum metrology demonstrates that atomic references for precision measurements have exceptional sensitivity and self-calibrating behavior. Microwave sensing in particular is reliant on antenna calibration and requires sophisticated signal processing to attempt to distinguish between incoherent thermal radiation and coherent fields. Prior to this work, state-of-the-art microwave sensitivity measurements using atomic vapors relied on experimental techniques to reduce the laser linewidth, as the optical linewidths dominate the atomic linewidths by many orders of magnitude. This work applied techniques from NMR to decouple the sensitivity from the optics: which is enabled by the long lifetime of the Rydberg state.
