Abstract: Random numbers are essential part in many areas such as statistic, lottery, gaming, marketing, computer simulation and cryptography. Therefore, there are numbers of random number generators have been proposed, most of them are not truly random. Exploiting the nondeterministic and stochastic quantum mechanics used to generate true random numbers. In this study, we propose a Quantum Random Numbers Generator (QRNG) based on a combination of different quantum effects of light. The proposed QRNG design splits the laser beam into two beams, each of which has a different intensity of quantum phase by using polarization technique. These intensities have independent phases. These phases translated into random amplitude variations using the interference of light of these two beams. We take advantage of this output phenomenon to produce true random number. The variation of these amplitudes are following Gaussian distribution of random values that are symmetric to a mean of zero. The results followed by post processing to maximize the randomness using min-entropy evaluation and optimized using Toeplitz random extractor which is theoretically provable random extractor. These results tested using NIST (National Institute of Standards and Technology) test suite for random numbers which pass all 16 tests successfully.
