This dataset comprises data collected from a research project whose core goal is to develop a high-rate, anti-interference Quantum Key Distribution (QKD) system. The project focuses on breaking through core technologies including scheme design for resisting channel disturbances and improving system operating rate, studying compensation mechanisms for channel polarization perturbations, designing and developing phase codecs that meet high-rate operating requirements and can effectively resist channel polarization interference, developing adaptive disturbance-compensated encoding and decoding schemes, high-stability low-time-jitter decoy-state light sources, high-precision high-bandwidth phase modulation modules, high-speed low-noise single-photon detection and high-speed system control and other core components and related technologies, as well as conducting practical integration and testing of the QKD system.
The dataset is organized and submitted mainly based on the research contents of Project 2, which is divided into three aspects: scheme design and verification of high-speed anti-interference QKD systems, design of key technologies and units, control, integration and testing.
The indicators corresponding to Project 2 of this dataset are: a QKD system with bit error rate (BER) variation ≤2% and operating frequency ≥5GHz under the condition of random channel disturbances in the range of 0.1Hz~1kHz; the duty cycle of key distribution time ≥90%, the duty cycle of key distribution time ≥90%, the secure key generation rate reaches 3Mbps under 50-kilometer optical fiber channel, and the long-term average BER of system signal states ≤3%; the achievement corresponding to Project 2 is a high-speed anti-interference QKD experimental system.
The data was mainly collected at the Key Laboratory of Quantum Information, Chinese Academy of Sciences. Theoretical calculations and simulations were conducted using professional software such as MATLAB, and data was collected via instruments including oscilloscopes, single-photon detectors and network analyzers, then processed by computers.
