Abstract

We present an optical quantum random number generator (QRNG) based on the digitized time interval between random photon arrivals. By tailoring the photon flux of the laser diode, the statistics of the waiting-time distribution are altered to approximate the ideal, uniform case. This greatly reduces the need for post-processing, and enables fast, secure quantum random number generation at rates exceeding 110 Mbit/s.

摘要

我们展示了一种基于随机光子到达之间数字化时间间隔的光学量子随机数发生器（QRNG）。通过调整激光二极管的光子通量，等待时间分布的统计特性被改变，以近似理想的均匀情况。这大大减少了后处理的需求，并能够以超过110 Mbit/s的速率进行快速、安全的量子随机数生成。
