“…Both the amplitude and phase of a weakly modulated RF field [3,14] can be detected at higher modulation rates limited only by the relaxation time of the atom. This limitation can be improved upon by using multiple optical beam paths through the vapor cell or multiple receiver cells [15]. The detection sensitivity can be improved by controlling laser stability in terms of laser frequency locking and laser linewidth, together with using low noise photodiodes, and using homodyne [16] and heterodyne [17] detection methods.…”

The numerical model has been developed for atomic ladder (cascade) systems, which proves to be suitable for Rydberg RF sensors.This model is designed with the capability to be extended to N-level non-thermal atomic systems with ease. The adaptability of this model to Rydberg RF sensors is validated by comparing its results with those of earlier reported experiments. The numerical model here provides a good approximation to the experimental results. Thus, such a dynamic model can be useful for quantum technologists in designing, optimising, and developing the Rydberg RF-based sensors in a user-friendly manner.

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 applications to atom-based measurements of dc and ac voltage and the calibration of voltage instrumentation. We present experimental results for different atomic states that allow for dc and ac voltage measurements ranging from 0 V to 12 V. A Rydberg atom-based voltage standard could become an alternative calibration method with more favorable size, weight, power consumption, and cost compared to the more precise Josephson voltage standard. In this study, we also demonstrate how the voltage measurements can be utilized to determine the atomic polarizability for the Rydberg states. The Rydberg atom-based voltage measurement technology would become a complimentary method for dissemination of the voltage scale directly to the end user.

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 around an atomic vapor-cell filled with cesium atoms for E-field measurements at 1.3 GHz. The SRR provides a factor of 100 in the enhancement of the E-field measurement sensitivity. Using electromagnetically induced transparency (EIT) with Aulter-Townes splitting, E-field measurements down to 5 mV/m are demonstrated with the SRR, while in the absence of the SRR, the minimal detectable field is 500 mV/m. We demonstrate that by combining EIT with a heterodyne Rydberg atom-based mixer approach, the SRR allows for the a sensitivity of 5.5 µV/m √ Hz, which is two-orders of magnitude improvement in sensitivity than when the SRR is not used. FIG. 1. Vapor cell place inside the split-ring resonator (SRR). The insert shows the dimension of the SRR.
