Abstract:
In recent years, the application of Rydberg atoms in microwave measurement has emerged as a research hotspot in quantum metrology. Compared to traditional microwave sensing technology, Rydberg atomic systems demonstrate higher sensitivity, stronger anti-interference capabilities, and unique quantum traceability. These advantages give Rydberg atoms great potential in microwave measurements. Despite these advantages, the complex energy level structure of Rydberg atomic systems and their diverse interactions with electromagnetic waves pose challenges for engineering applications. Currently, the application of “atomic aperture” sensing technology based on Rydberg atoms in traditional microwave sensing is still in its initial stages, with significant room for improvement. To fully leverage the advantages of Rydberg atoms in microwave measurement and address their limitations in practical applications, we discuss the prospects of Rydberg atomic systems in current electromagnetic wave transceiver technologies, building on previous research findings. With ongoing technological advancements, Rydberg atoms are expected to achieve precise measurements across a wider range of frequency bands, providing robust support for wireless communication, radar detection, and other related fields.
