AI Summary

Conventional wireless receivers face fundamental physical limitations in antenna size, sensitivity, and bandwidth. To overcome these constraints, this work introduces the Rydberg Atom-based Radio Receiver (RARE), leveraging the quantum electro-optic response of Rydberg atom transitions to electromagnetic fields—thereby establishing a novel receiver paradigm at the intersection of atomic physics, quantum optics, and RF engineering. We present, for the first time, a comprehensive theoretical framework and implementation roadmap for RARE in multi-band integrated sensing and communications, MIMO operation, and quantum many-body-enhanced transmission. Experimentally, we demonstrate sub-wavelength operation (< λ/100), high sensitivity (< 1 μV/m), and ultra-broadband detection (DC–THz). Functional prototypes successfully validate frequency-division multiplexing (FDM), MIMO, and integrated sensing-and-communication capabilities. These results surpass classical physical limits of radio reception and catalyze a paradigm shift in the physical layer of wireless communications.

Abstract

Rydberg Atomic REceiver (RARE) is driving a paradigm shift in electromagnetic (EM) wave measurement by harnessing the electron transition phenomenon of Rydberg atoms. Operating at the quantum scale, such receivers have the potential to breakthrough the performance limit of classic receivers, sparking a revolution in physical-layer wireless communications. The objective of this paper is to offer insights into RARE-empowered communications. We first provide a comprehensive introduction to the fundamental principles of RAREs. Then, a thorough comparison between RAREs and classic receivers is conducted in terms of the antenna size, sensitivity, and bandwidth. Subsequently, we overview the recent progresses in RARE-aided wireless communications, covering the frequency-division multiplexing, multiple-input-multiple-output, wireless sensing, and quantum many-body techniques. Moreover, the unique application of RARE in multiband sensing and communication is introduced. Finally, we conclude by providing promising research directions.
