论文摘要

这项工作报告了真实量子随机数生成器的设置,表征和数据处理。作为一个随机性来源,使用了纯量子真空状态,它被激光束扩大。研究了系统的性能和行为以及寄生误差。为了优化对数据的利用,它们是傅立叶转换的,并作为频率幅度进一步处理。计算该数据的可提取熵是为了通过哈希消除非随机信号的贡献。该系统能够以25 Gbit/s的速率生成真实和唯一的随机数,从而超过以前的实现。

This work reports on setup, characterisation and data processing of a true quantum random number generator. As a randomness source a pure quantum vacuum state of light is used, which is amplified by a laser beam. Performance and behaviour of the system as well as parasitic errors are investigated. For an optimized exploitation of the data they are Fourier-transformed and processed further as frequency amplitudes. The extractable entropy in that data is calculated to allow for elimination of non-random signal contributions by hashing. The system is able to produce true and unique random numbers at a rate of 25 Gbit/s and thus outperforms previous implementations considerably.
