我们提出了一个高质量的无偏置量子随机数发生器（QRNG），根据在衰减光的采样时间间隔内的光子探测事件的数量，选择性地使用光子到达时间。理论分析和实验验证表明，该随机数产生方法不需要进一步的后处理，就能很好地消除偏差和相关性，而且所产生的随机数能通过标准的随机性检验。对该方法进行了理论分析和实验验证，其传输速率可达45 Mb/s。
We present a high-quality bias-free quantum random number generator (QRNG) using photon arrival time selectively, in accordance with the number of photon detection events within a sampling time interval in attenuated light. It is well shown in both theoretical analysis and experimental verification that this random number production method eliminates both bias and correlation perfectly without more postprocessing and that the random number can clearly pass the standard randomness tests. We fulfill theoretical analysis and experimental verification of the method whose rate can reach up to 45 Mb/s.
