Observation of alignment tensor effects in metastability-exchange collisions with highly polarized 3He ensembles
Yida Sha, Kaiwen Yi, Xingqing Jin +2
Highly polarized 3He ensembles prepared by metastability-exchange optical pumping (MEOP) have been widely used in precision measurements and fundamental physics. Metastability-exch…
Effective Faraday interaction between light and Helium-3 nuclear spins in a multi-pass cell
Kaiwen Yi, Yida Sha, Zejia Lin +2
Helium-3 nuclear spins form an exceptionally stable quantum system with extremely long coherence time, offering exciting opportunities for quantum technologies. In particular, nucl…
Observation of Mollow quintuplet in F=3/2 hyperfine structure state of 3He atomic cell
Yuanzhi Zhan, Xiang Peng, Sheng Li +3
We experimentally observed the Mollow quintuplet (MQ) in F=3/2 hyperfine structure state of 3He atoms. The metastability-exchange collisions (MECs) transfer the Mollow Triplet (MT)…
Observation of Mollow triplet with metastability exchange collisions in 3He atoms
Yuanzhi Zhan, Xiang Peng, Sheng Li +3
We study the dressed states of 3He atoms and experimentally observe the Mollow triplet (MT) induced with an ultra-low-frequency (ULF) oscillating magnetic field as low as 4 Hz. The…
Light Source Monitoring in Quantum Key Distribution with Single Photon Detector at Room Temperature
Gan Wang, Zhengyu Li, Yucheng Qiao +3
Photon number resolving monitoring is a practical light source monitoring scheme in QKD systems, which reduces the impacts from untrusted sources effectively. This scheme requires…
Non-Gaussian postselection and virtual photon subtraction in continuous-variable quantum key distribution
Zhengyu Li, Yi-Chen Zhang, Xiangyu Wang +3
Photon subtraction can enhance the performance of continuous-variable quantum key distribution (CV QKD). However, the enhancement effect will be reduced by the imperfections of pra…
