Photorefractive-based on-chip optical power limiter against light-injection attacks in quantum key distribution
Min Chen, Hong-Yan Song, Jia-Lin Chen +10
Light-injection attacks pose critical security threats to quantum key distribution (QKD) systems. Conventional countermeasures, such as isolators, filters, and optical power monito…
5-GHz chip-based quantum key distribution with 1Mbps secure key rate over 150 km
Guo-Wei Zhang, Sheng-Teng Zheng, You Xiao +16
Quantum key distribution (QKD) enables secure communication by harnessing the fundamental principles of quantum physics, which inherently guarantee information-theoretic security a…
Microcomb-driven large-scale fully connected quantum network
Fang-Xiang Wang, Sheng-Teng Zheng, Long Huang +15
Fully connected quantum networks enable simultaneously connecting every user to every other user and are the most versatile and robust networking architecture. However, the scalabi…
Optical information encryption using general temporal ghost imaging with practical experimental condition
Juan Wu, Xiaohai Zhan, Fang-Xiang Wang +5
Temporal Ghost Imaging (TGI), which reconstructs fast temporal signals using a slow detector, holds significant potential in optical communication, high-speed imaging, and quantum…
