Methods for enhancing data sampling rates in spatiotemporal multiplexed Rydberg sensors

This paper reports on progress in methods for achieving data sampling rates in quantum RF Rydberg sensors that can exceed limitations imposed on current sensor designs by atomic relaxation rates. The spatiotemporal multiplexing technique samples fresh atoms with each probe laser pulse, significantly enhancing signal-to-noise ratio and enabling high-bandwidth RF detection. We report on preliminary feasibility of achieving an up to 20 MHz data sampling rate, along with a super-sampling technique, and a pulsed coupling method to further improve the data sampling rates of Rydberg receivers.
