摘要
近年来,里德堡原子在微波测量领域的应用逐渐崭露头角,成为了量子精密测量领域的研究热点。相较于传统微波传感技术,里德堡原子体系展现出了更高的灵敏度、更强的抗干扰能力以及独特的量子可溯源性。这些优势使得里德堡原子在微波测量中具有巨大的潜力。尽管里德堡原子体系具有诸多优势,但其复杂的能级结构和与电磁波的多样相互作用给工程应用带来了挑战。目前,基于里德堡原子的“原子孔径”传感技术在传统微波传感领域的应用仍处于初级阶段,有着巨大的提升空间。为了充分发挥里德堡原子在微波测量中的优势,并解决其在实际应用中的局限性,在总结前期研究成果的基础上,探讨了里德堡原子体系在当前电磁波收发体制中的应用前景。随着技术的不断进步,里德堡原子有望在更广泛的频段内实现精确测量,为无线通信、雷达探测等领域提供有力支持。
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.
