- Abstract: Rydberg electric field sensors exploit the large number of Rydberg resonances
to provide sensitivity over a broad range of the electromagnetic spectrum.
However, due to the difficulty of accessing resonant Rydberg states at
ultra-high frequency (UHF) and below, ubiquitous bands in the world's current
wireless communications infrastructure, they currently fall short in
sensitivity in this range. We present a resonant Rydberg electric field sensor
operating in the UHF band using a dual-optical dual-microwave spectroscopy
scheme. Adding an additional microwave photon allows us to access transitions
between Rydberg states with higher angular momentum ($L = 3 \rightarrow 4$),
which have lower resonant frequencies than transitions typically used in
Rydberg sensors. We discuss the applicability of this type of sensor across the
UHF band and below, and measure the resonant sensitivity of our system at 2.3
GHz to be 70(5) $\mu$Vm$^{-1}\text{Hz}^{-1/2}$, 50 times better than the
measured sensitivity with a far off-resonant probing scheme at this frequency.
We also show the effectiveness of this sensing scheme by measuring Sirius XM
satellite radio (2.320 - 2.345 GHz) received outside the laboratory and
rebroadcast onto the atoms.

We find that the three-photon system boasts much narrower line widths compared to the conventional two-photon EIT.
In addition to this, we calculate the expected sensitivity for the two-photon Rydberg sensor and find that the best achievable sensitivity is over an order of magnitude better than the current measured values of 5 uV/m/Hz.
