We report upon the realization of a novel fast nondeterministic random number generator whose randomness relies on the intrinsic randomness of the quantum physical processes of photonic emission in semiconductors and subsequent detection by the photoelectric effect. Timing information of detected photons is used to generate binary random digits-bits. The bit extraction method based on the restartable clock method theoretically eliminates both bias and autocorrelation while reaching efficiency of almost 0.5 bits per random event. A prototype has been built and statistically tested.
我们报告了一种新型快速非确定性随机数发生器的实现，其随机性依赖于半导体中光子发射的量子物理过程以及随后通过光电效应进行检测的内在随机性。检测到的光子的定时信息用于生成二进制随机数字——比特。基于可重启时钟方法的比特提取方法理论上消除了偏差和自相关，同时每个随机事件的效率几乎达到0.5比特。已构建了一个原型并进行了统计测试。
