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…
Fault-Tolerant Quantum Key Distribution: Enabling Overclocked Modulation
Feng-Yu Lu, Jia-Xuan Li, Ze-Hao Wang +8
Implementation security, higher generation rate, and lower cost are primary missions in the domain of quantum key distributions in recent years. However, simultaneously achieving r…
Relativistic Position Verification with Coherent States
Guan-Jie Fan-Yuan, Yang-Guang Shan, Cong Zhang +10
Determining the position of an entity is a fundamental prerequisite for nearly all activities. Classical means, however, have been proven incapable of providing secure position ver…
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…
Measurement-device-independent quantum key distribution with asymmetric sources
Jia-Ju Deng, Feng-Yu Lu, Zhen-Qiu Zhong +7
Measurement-device-independent quantum key distribution (MDI-QKD), which eliminates all the attacks from the eavesdropper to the measurement party, has been one of the most promisi…
