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…
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…
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…
Fast qubit-based frequency recovery algorithm for quantum key distribution
Feng-Yu Lu, Zheng-Kai Huang, Jia-Jv Deng +7
Clock synchronization serves as a foundational subsystem in quantum key distribution (QKD). The recently proposed Qubit-based synchronization (Qubit4Sync) has opportunities in elim…
Experimental demonstration of drone-based quantum key distribution
Xiao-Hui Tian, Ran Yang, Hua-Ying Liu +14
Quantum state transferring has been demonstrated using drones via entanglement distribution. Here we demonstrate the first drone-based quantum task, for quantum key distribution (Q…
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…
