Abstract

Generation of unbiased random numbers using classical light sources is presented. Bit assignment is based on detecting odd and even number of photons in a time interval, with odd detection assigned bit value ‘0’ and even detection assigned bit value ‘1’. The effect of dead time on the detected number photons for varying incoming photon rates is studied numerically. Random number generation is experimentally demonstrated on the classical sources : laser, laser diode, light emitting diode, ambient room light, and ambient sunlight, for varying incoming photon rates, using a single photon avalanche diode. The generated random numbers are shown to successfully pass the NIST statistical suite with a significance level of 0.01, without any requirement for post processing.

后期处理自由随机数生成使用经典和环境光源

介绍了利用经典光源产生无偏随机数的方法。位分配是基于在一个时间间隔内检测奇数和偶数光子，奇数检测分配位值为0，偶数检测分配位值为1。数值研究了不同入射光子速率下死区时间对检测光子数的影响。利用单光子雪崩二极管，在激光、激光二极管、发光二极管、环境室内光和环境太阳光等经典光源上，对不同的入射光子速率进行了随机数生成实验验证。生成的随机数成功通过NIST统计套件，显著性水平为0.01，不需要任何后处理。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
