“…In the higher-frequency range, with an auxiliary MW field detuned from the target field by approximately 1.4 GHz introduced into a four-level Rydberg atom-based MW E-field sensing system, the performance of this quantum microwave electrometry system was improved to 31 µV•cm −1 for enlarged EIT-AT splitting [64]. A similar setup with the introduction of a resonant microwave field but with further optimization of the power ratio of the two microwave fields was also investigated, where a minimum detectable MW E-field of 6.71 µV•cm −1 was achieved [65]. The three-laser Rydberg EIA-based heterodyne MW sensor achieved a minimum detectable E-field of 78.9 nV•cm −1 within a timescale of 500 ms and a sensitivity of 55.79 nV•cm −1 Hz −1/2 [66].…”

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.

Metamaterials are a class of non-natural materials with special properties, the microstructure of which does not exist in nature. By artificially designing the structure of such materials, they can acquire electromagnetic properties that conventional materials in nature do not have. Electromagnetically induced transparency refers to the process of quantum interference effect between atomic energy levels in microscopic systems, which makes an energy-transmitting window appear in the original energy-absorbing region, simply put, a medium strongly absorbs a certain frequency of the light beam, and when another light beam is applied, the absorption of the first light beam by the medium will be greatly reduced or no longer absorbed. This phenomenon is called electromagnetically induced transparency, or EIT for short. In this paper, we combine the graphene material with the EIT structure to improve the manipulability of the EIT structure and obtain a controllable EIT structure based on the multi-mode coupled EIT extension.

“…Several methods have been developed to push the lower limit of EIT-AT splitting measurement for MW electric fields. These include the cold atom method, [27,28] MW frequency detuning, [29] auxiliary MW field, [30,31] three-photon excitation [32] and amplitude modulation (AM) dispersion. [33] Laser-cooled cold atoms, with their lower temperatures and reduced dephasing rates, significantly narrow the Rydberg EIT linewidth, enhancing precision.…”

“…[30] Jin-peng Yuan et al enhanced sensitivity by two orders of magnitude using an auxiliary field at the signal MW frequency. [31] Mingzhi Han et al's bichromatic EIT in Rydberg atoms improved the minimum detectable MW electric field strength by about 3 times. [35] Fabian Ripka et al achieved a 500 kHz EIT linewidth in cesium atomic vapor cells with collinear three-photon excitation, advancing the EIT-AT split linear region's lower limit by one order of magnitude.…”

We have theoretically and experimentally studied the dispersive signal of the Rydberg atomic electromagnetically induced transparency (EIT) - Autler-Townes (AT) splitting spectra obtained using amplitude modulation of the microwave (MW) electric field. In addition to the two zero-crossing points interval $\Delta f_{\text{zeros}}$, the dispersion signal has two positive maxima with an interval defined as the shoulder interval $\Delta f_{\text{sho}}$, which is theoretically expected to be used to measure a much weaker MW electric field. The relationship of MW field strength $E_{\text{MW}}$ and $\Delta f_{\text{sho}}$ are experimentally studied at the MW frequencies of 31.6 GHz and 9.2 GHz respectively. The results show that $\Delta f_{\text{sho}}$ can be used to character the much weaker $E_{\text{MW}}$ than that of $\Delta f_{\text{zeros}}$ and the traditional EIT-AT splitting interval $\Delta f_{\text{m}}$, the minimum $E_{\text{MW}}$ measured by $\Delta f_{\text{sho}}$ is about 30 times smaller than that by $\Delta f_{\text{m}}$. As an example, the minimum $E_{\text{MW}}$ at 9.2 GHz that can be characterized by $\Delta f_{\text{sho}}$ is 0.056 mV/cm, which is the minimum value characterized by frequency interval using vapour cell without adding any auxiliary fields. The proposed method can improve the weak limit and sensitivity of $E_{\text{MW}}$ measured by spectral frequency interval, which is important in the direct measurement of weak $E_{\text{MW}}$.
