“…5 is ∆E psn = 1.6 µV/m/ √ Hz, a factor of 40 higher than E qpn . Technical improvements that will be pursued in future work to reach the photon shot noise limit include intensity stabilization and the addition of a laser to repump ground state population [50] and potentially comb-based optical probing [65].…”

“…For example, MW signal strength has been proven to enhance microwave measurement in Rydberg atoms [ 20 ]. An enhanced transmission signal is obtained using self-heterodyne spectroscopy [ 29 ], and the quadratic changes in peak amplitudes demonstrates a minimum detectable RF electromagnetic field strength. We notice some interesting results in three-photon coherence [ 30 , 31 , 32 , 33 ], which provides a new way method for EIT-related applications, such as observation of three-photon electromagnetically induced absorption (TPEIA) [ 34 ] in atomic systems, constructive interference in the three-photon absorption [ 35 , 36 ], demonstration of three-photon coherence condition [ 37 , 38 , 39 ], and its extension to Rydberg atoms [ 40 ].…”

A scheme for the measurement of a microwave (MW) electric field is proposed via multi-photon coherence in Rydberg atoms. It is based on the three-photon electromagnetically induced absorption (TPEIA) spectrum. In this process, the multi-photon produces a narrow absorption peak, which has a larger magnitude than the electromagnetically induced transparency (EIT) peak under the same conditions. The TPEIA peak is sensitive to MW fields, and can be used to measure MW electric field strength. We found that the magnitude of TPEIA peaks shows a linear relationship with the MW field strength. The simulation results show that the minimum detectable strength of the MW fields is about 1/10 of that based on an common EIT effect, and the probe sensitivity could be improved by about four times. Furthermore, the MW sensing based on three-photon coherence seems to be robust against the changes in the control field and shows a broad tunability, and the scheme may be useful for designing novel MW sensing devices.
