Yb/Sr optical clock comparison at 2.2E-18 uncertainty over a 1350-km fiber link
Lei Hou, Xiang-Pei Liu, Zhuan-Xian Xiong +32
Redefining the International system of Units (SI) second requires independent frequency-ratio measurements between clocks based on different laboratories, with an overall uncertain…
High-Performance Quantum Frequency Conversion from Ultraviolet to Telecom Band
Yi Yang, Bin Wang, Ji-Chao Lin +10
Quantum frequency conversion (QFC) is essential for bridging the spectral gap between stationary qubits and low-loss optical communication channels. In this work, we demonstrate a…
E-21 Level Instability Frequency Dissemination over 2067 km noisy Telecommunication Infrastructure
Fa-Xi Chen, Li-Bo Li, Jiu-Peng Chen +9
The realization of ultra stable optical frequency transmission through fiber networks is critical for advancing global optical frequency standards and enabling applications such as…
113 km absolute ranging with nanometer precision
Yan-Wei Chen, Meng-Zhe Lian, Jin-Jian Han +15
Accurate long-distance ranging is crucial for diverse applications, including satellite formation flying, very-long-baseline interferometry, gravitational-wave observatory, geograp…
Dual-comb spectroscopy over 100km open-air path
Jin-Jian Han, Wei Zhong, Ruo-Can Zhao +19
Satellite-based greenhouse gases (GHG) sensing technologies play a critical role in the study of global carbon emissions and climate change. However, none of the existing satellite…
113 km Free-Space Time-Frequency Dissemination at the 19th Decimal Instability
Qi Shen, Jian-Yu Guan, Ji-Gang Ren +28
Optical clock networks play important roles in various fields, such as precise navigation, redefinition of "second" unit, and gravitational tests. To establish a global-scale optic…
Time-Frequency Transfer through a 70 dB Free Space Channel: Towards Satellite-Ground Time Dissemination
Qi Shen, Jian-Yu Guan, Ting Zeng +15
Time and frequency transfer lies at the heart of the field of metrology. Compared to current microwave dissemination such as GPS, optical domain dissemination can provide more than…
