Abstract: The quantum precision measurement system based on atomic ensembles possesses high accuracy and stability, making it one of the directions for the development of advanced measurement systems in the future. Among them, electric field measurements based on Rydberg atoms exhibit characteristics such as high sensitivity, ultra-wideband capability, and excellent electrical isolation, and have gained widespread attention in recent years. However, current research on electric field quantum precision measurement based on Rydberg atoms is mainly focused on the microwave frequency range, with limited studies on low-frequency electric field measurements below GHz. Given the significant scientific and practical value of high-sensitivity detection in DC-MHz frequency range electric fields in many areas such as geophysical exploration, biosensing, defense communication, and space exploration, this article reviews the recent progress in novel antenna research in the DC-MHz frequency range, summarizes the development trends of atomic antenna technology in recent years, outlines the principles of low-frequency electric field measurement based on Rydberg atoms, and discusses the potential improvement strategies for key performance indicators such as sensitivity and instantaneous bandwidth of atomic antennas, as well as their potential applications in the field of low-frequency detection in the future.

Key words: quantum information, quantum precision measurement, Rydberg atom, atomic antennas; low-frequency electromagnetic field
