The superconductor random number generator (SRNG) can generate unpredictable and true random numbers at speeds of greater than 30 Gbps. Parallelization of SRNGs requires individual adjustment of the operating points of each SRNG to the optimal point. We have proposed a method to parallelize the SRNGs without adjusting their operating points individually. However, it has a problem of deteriorating the randomness of the output random number sequences. In this presentation, we discuss a method to generate high-quality random numbers from parallelized SRNGs without individual adjustment of the operating points.
