We present a thermal velocity sampling method for calculating Doppler-broadened atomic spectra, which more efficiently reaches convergence than regular velocity weighted sampling. The method uses equal-population sampling of the 1D thermal distributi

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 demo

We investigate the use of a split-ring resonator (SRR) incorporated with an atomic-vapor cell to improve the sensitivity and the minimal detectable electric (E) field of Rydberg atom-based sensors. In this approach, a sub-wavelength SRR is placed aro

We investigate the Stark shift in Rydberg rubidium atoms through electromagnetically induced transparency for the measurement of direct current (dc) and 60 Hz alternating current (ac) voltages. This technique has direct application to the calibration

We experimentally demonstrate an imaging technique based on quantum noise modification after interaction with an opaque object. By using a homodyne-like detection scheme, we eliminate the detrimental effect of the camera's dark noise, making this app

We determine DC and AC electric field strengths through measurements of Stark shifts in Rydberg electromagnetically-induced transparency. This demonstrates the potential for Rydberg atom-based calibrations of AC/DC voltage sources from 0-12 V.
