A high-precision microwave detection technology using atoms is an essential foundation in future communication technologies. In this study, improvement of microwave detection sensitivity by atoms is realized. First, an open-loop resonator is designed based on finite element simulation and subsequently fabricated; then, the microwave electric field intensity is measured with and without the resonator, based on the electromagnetically induced transparency Autler-Townes effect. The microwave electric field with different input powers is measured, and the improvement achieved with the resonator is verified. The optimal detection sensitivity is improved from 2.14(5) to 0.73(4)V/m, and the sensitivity is improved by a factor of approximately 2.9. These results provide a practical reference for the application of high-precision detection of microwave electric fields with atoms and atomic microwave communication in the future.

“…The recent use of a sub-wavelength split-ring resonator (SRR) incorporated with an atomic vapor cell provides 100 times enhancement of the E-field measurement sensitivity. A sensitivity of 55 nV•cm −1 Hz −1/2 was achieved by combining EIT with a heterodyne Rydberg atom-based mixer approach [86].…”

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.

Rydberg atom can respond to weak microwave electric field signal in real-time by using its electromagnetically induced transparency effect to realize down conversion of space microwave electric field signal, which can be used as a superheterodyne receiver. The Rydberg atom superheterodyne receiver is a new receiving system composed of Rydberg atoms, photodetectors, and electronic information processing modules. Presently, domestic and foreign scholars have conducted in-depth research on the physical response mechanism of Rydberg atomic superheterodyne receiving technology. However, no complete receiving link analysis model has been established, which is not conducive to optimizing its system performance. Based on the physical mechanism of the Rydberg atom responding to the microwave electric field, this paper introduces the concept of intrinsic expansion coefficient, establishes and experimentally verifies the receiving link model of the Rydberg atom superheterodyne receiver, and briefly discusses the influence of the intrinsic expansion coefficient on the system sensitivity and response characteristics, which provides theoretical guidance for the optimization of the performance of the Rydberg atom superheterodyne receiving system. Last, the Rydberg atomic and the electronic receiving links' sensitivity performance is discussed and compared.
