90%-Efficient Optical Storage in a Rare-Earth Crystal with a Low-Loss Impedance-Matched Cavity
Weiye Sun, Fudong Wang, Mucheng Guo +7
High-efficiency optical storage in rare-earth-ion-doped crystals is challenging because of their typically weak optical absorption,which makes cavity-enhanced memories highly sensi…
Slow-light-enhanced Atomic Frequency Comb Quantum Memory in Stoichiometric EuCl 6DO
Zongfeng Li, Wanting Xiao, Mucheng Guo +3
Rare-earth-doped crystals are promising candidates for quantum storage, yet their performance in free-space configurations is fundamentally restricted by low optical depth. Here, w…
Realization of Backward Retrieval in a Stark-modulated Spin-wave Quantum Memory
Zhenqi Xu, Mucheng Guo, Weiye Sun +5
We report the first experimental realization of backward retrieval in a spin-wave quantum memory based on a Stark-echo-modulated protocol in Eu3+:Y2SiO5. By using Stark control, we…
Ultralong-lived Coherent States in Eu:YO Optical Ceramics for Quantum Memories
Shuping Liu, Miaomiao Ren, Wanting Xiao +8
Rare earth ions (REI) in solid materials are among the leading systems for quantum technology applications. However, developing practical REI quantum devices with long-lived cohere…
Optical coherence and hyperfine structure of the 7F0-5D0 transition in EuCaWO4
Xiantong An, Weiye Sun, Zhehao Xu +6
Rare-earth ions doped in crystals with low nuclear-spin densities are highly promising candidates for quantum technology applications. In this study, we investigated the spectrosco…
