| 摘 要： | 在远距离量子密钥分发(QKD)系统中,使用基于场可编程门阵列(FPGA,field programmable gatearray)的串行器/解串器(SER/DES,serializer/deserializer)技术完成了500 Mbit/s的量子传输速率,利用低频(2 MHz)的同步信号完成对发射方和接收方的同步。根据QKD实验的需要,完成了信号甄别、伪随机数产生器、时间同步和数据编码等功能,成功搭建了基于诱骗态的远距离QKD系统。

| Abstract: | At the long-distance quantum key distribution(QKD) experiments,high-speed quantum transmission is needed.In this paper,quantum transmission rate at 500 Mbit/s is fulfilled based on SER/DES module inside FPGA,and a time synchronization design between transmitter and receiver using a low frequency sync-pulse(2 MHz) is proposed.For the experiment′s requirements,signal discriminator,pseudo-random number generator,time synchronization and data coding are developed.This design has been applied successfully to build decoy-state based long-distance QKD experiment. |
