Doppler-enhanced superheterodyne Rydberg microwave receiver
Yuwen Yin, Ruimin Chen, Shibing Ji +7
We report the enhanced sensitivity of the Rydberg microwave (MW) receiver by exploiting the Doppler effect in a vapor cell. A two-photon Rydberg ladder scheme is implemented via th…
Arbitrary Instantaneous Bandwidth Microwave Receiver via Scalable Rydberg Vapor Cell Array with Stark Comb
Yuechun Jiao, Yuwen Yin, Yunhui He +7
Rydberg atoms have great potential for microwave (MW) measurements due to their high sensitivity, broad carrier bandwidth, and traceability. However, the narrow instantaneous bandw…
Thermal resonance-enhanced transparency in room temperature Rydberg gases
Jinlian Hu, Yuechun Jiao, Yuwen Yin +6
We report the enhanced optical transmission in the coherent, off-resonant excitation of Rydberg atom gases at room temperature via a two-photon process. Here thermal resonance-enha…
Exploring quantum sensing for fine-grained liquid recognition
Yuechun Jiao, Jinlian Hu, Zitong Lan +9
Recent years have witnessed the use of pervasive wireless signals (e.g., Wi-Fi, RFID, and mmWave) for sensing purposes. Due to its non-intrusive characteristic, wireless sensing pl…
Continuous broadband Rydberg receiver using AC Stark shifts and Floquet States
Danni Song, Yuechun Jiao, Jinlian Hu +6
We demonstrate the continuous broadband microwave receivers based on AC Stark shifts and Floquet States of Rydberg levels in a cesium atomic vapor cell. The resonant transition fre…
