摘　　要：量子密钥分发系统的码率太低,研究用交织技术和插值技术来扩展已有量子密钥库的容量,以期提高量子保密通信系统的量子密钥生成速率。初步仿真结果显示:采用交织技术和插值技术能扩展随机序列,且其随机性能不变。数字信号处理相关理论与技术是一种扩展量子密钥库的有效方法。The rates of quantum key distribution systems are too low, the interleaving technique and interpolation technique are used to extend the capacity of quantum key warehouse in order to advance the quantum key rates of quantum security communication systems. The simulation shows the interleaving technique and interpolation technique can extend random sequences and their randomicity are invariable. The correlative theory and technique of digital signal processing is an effective method of extending quantum key warehouse.
