Single-sideband-interference twin-field quantum key distribution without global phase locking
Xingjian Li, Bingkun Wang, Jianyong Hu +10
Twin-field quantum key distribution (TF QKD) can overcome the fundamental rate loss limit of repeaterless quantum links, but its practical deployment has long been hindered by the…
High-resolution wide-field magnetic imaging with sparse sampling using nitrogen-vacancy centers
Keqing Liu, Jiazhao Tian, Bokun Duan +7
Nitrogen-vacancy (NV) centers in diamond enable quantitative magnetic imaging, yet practical implementations must balance spatial resolution against acquisition time (and thus per-…
Electric-field control of pure spin photocurrent in germanene
Yaqing Yang, Zhen Zhang, Liwen Zhang +4
The electrical control of pure spin current remains a central challenge in spintronics, particularly in time-reversal symmetric systems composed of nonmagnetic elements, where spin…
Stable self-charged perovskite quantum rods for liquid laser with near-zero threshold
Jialu Li, Xue Han, Wenjie Wang +18
Colloidal quantum dots (QDs) are promising optical gain materials that require further threshold reduction to realize their full potential. While QD charging theoretically reduces…
On-demand manipulation of superbunching emission from colloidal quantum dots and its application in noise-resistance correlated biphoton imaging
Yunrui Song, Chengbing Qin, Yuanyuan Li +10
Superbunching effect with second-order correlations larger than 2, , indicating the N-photon bundles emission and strong correlation among photons, has a broad range…
Spatiotemporal Deep Learning Network for Photon-Level Block Compressed Sensing Imaging
Changzhi Yu, Shuangping Han, Kai Song +1
In this paper, we propose a spatiotemporal deep learning network for photon-level Block Compressed Sensing Imaging, aimed to address challenges such as signal loss, artifacts, and…
