AI-assisted hyper-dimensional broadband quantum memory with efficiency above 90% in warm atoms
Zeliang Wu, Jinxian Guo, Zhifei Yu +4
High-dimensional broadband quantum memory significantly expands quantum information processing capabilities, but the memory efficiency becomes insufficient when extended to high di…
Sensitivity-enhanced magnetometry using nitrogen-vacancy ensembles via adaptively complete transitions overlapping
Bao Chen, Bing Chen, Xinyi Zhu +3
Nitrogen-vacancy (NV) centers in diamond are suitable sensors of high-sensitivity magnetometry which have attracted much interest in recent years. Here, we demonstrate sensitivity-…
Sensing performance enhancement via asymmetric gain optimization in the atom-light hybrid interferometer
Zhifei Yu, Bo Fang, Shuying Chen +4
The SU (1,1)-type atom-light hybrid interferometer (SALHI) is a kind of interferometer that is sensitive to both the optical phase and atomic phase. However, the loss has been an u…
Effects of losses on the sensitivity of an actively correlated Mach-Zehnder interferometer
Qiang Wang, Gao-Feng Jiao, Zhifei Yu +3
We theoretically studied the quantum Cramér-Rao bound of an actively correlated Mach-Zehnder interferometer (ACMZI), where the quantum Fisher information obtained by the phase-aver…
High-performance Raman quantum memory with optimal control
Jinxian Guo, Xiaotian Feng, Peiyu Yang +4
Quantum memories with high efficiency and fidelity are essential for long-distance quantum communication and information processing. Techniques have been developed for quantum memo…
