“…The FDTD simulation results clearly demonstrate the differences between the two scenarios, with cell having a significant impact on the E-field homogeneity. To improve the homogeneity within the cell, consider using a vapor cell with perforated walls [47]. Overall, the relative dielectric constant ε r of cell wall is not equal to 1, which renders much larger electrical size.…”

Due to its large electric dipole moment, the Rydberg atom exhibits a strong response to weak electric fields, hence it is regarded as a highly promising atomic antenna. However, to enhance the reception sensitivity, split-ring resonators are needed normally, which will brings sensing blind spots. Thus it is not conducive to the application of full-coverage space communication. Here we propose that an atomic antenna with an asymmetric parallel-plate resonator, can not only enhance the received signal, but also eliminate sensing blind spots (pattern roundness can reach 7.8 dB while the split-ring resonator can be up to 39 dB). We analyze the influence of structural parameters on the field enhancement factor and directionality, and further discuss the limitation of the sensitivity by using thermal resistor noise theory.This work is expected to pave the way for the development of field-enhanced Rydberg atomic antennas that communicate without a blind spot.

“…The amplitude modulation of the MW field achieves a six-time improvement in the EIT-AT splitting resolution, where the minimum detectable MW Efield strength is 430 µV•cm −1 [51]. The three-photon readout scheme, which reduces the residual Doppler shifts to the order of magnitude of the Rydberg state decay times, extends the AT splitting regime of Rydberg atom-based radio-frequency (RF) electrometry to sense lower-RF E-field strengths [52,53]. However, the optimum sensitivity of quantum sensors based on the EIT of a three-level system was derived, showing clear boundaries.…”

Microwave electric ﬁeld sensing is of importance for a wide range of applications in areas of remote sensing, radar astronomy and communications. Over the past decade, Rydberg atoms, owing to their exaggerated response to microwave electric ﬁelds, plentiful optional energy levels and integratable preparation methods, have been used in ultra-sensitive, wide broadband, traceable, stealthy microwave electric ﬁeld sensing. This review ﬁrst introduces the basic concept of quantum sensing, properties of Rydberg atoms and principles of quantum sensing of microwave electric ﬁelds with Rydberg atoms. Then an overview of this very active research direction is gradually expanded, covering progresses of sensitivity and bandwidth in Rydberg atoms based microwave sensing, superheterodyne quantum sensing with microwave-dressed Rydberg atoms, quantum-enhanced sensing of microwave electric ﬁeld, recent advanced quantum measurement systems and approaches to further improve the performance of microwave electric ﬁeld sensing. Finally, a brief outlook on future development directions is discussed.

“…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 ]. To the best of our knowledge, little research involves MW metrology using TPEIA in Rydberg atoms.…”

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.
