Semi-Device-Independent Quantum Random Number Generator Resistant to General Attacks
Zhenguo Lu, Jundong Wu, Yu Zhang +4
Quantum random number generators (QRNGs) produce true random numbers based on the inherent randomness of quantum theory, rendering them a foundational segment of quantum cryptograp…
Continuous-variable quantum key distribution over 50.4 km fiber using integrated silicon photonic transmitter and receiver
Shuaishuai Liu, Yanxiang Jia, Yuqi Shi +7
Quantum key distribution (QKD) is the fastest-growing and relatively mature technology in the field of quantum information, enabling information-theoretically secure key distributi…
High-Performance Fully Passive Discrete-State Continuous-Variable Quantum Key Distribution With Local Local Oscillator
Yu Zhang, Xuyang Wang, Chenyang Li +5
We propose and demonstrate a fully passive discrete-state continuous-variable quantum key distribution (CV-QKD), which can eliminate all modulator side channels on the source side,…
Calibration of cascaded phase shifters using pairwise scan method in silicon photonics integrated chip
Yanxiang Jia, Xuyang Wang, Yizhuo Hou +5
Cascaded phase shifters (CPSs) based on silicon photonics integrated chips play important roles in quantum information processing tasks. Owing to an increase in the scale of silico…
