Design of high speed quantum random number acquisition system without post- processing based on automatic bias-correcting

In this article, a random number generator without post-processing, which uses the randomness of photon in optics quantum random source, is designed. The design employs feeble light to detect at single photon level. The pulse number detected by in fixed period obeys Possion distribution, but effect of electronic components and readout electronics distorts Possion distribution. Controlling mean count can eliminate bias to achieve unbiased in statistics. High quality and high speed random numbers using automatic bias-correcting technique is produced without post-processing and passes all standard tests relevant for random number generators, like NIST, Die hard.
