Abstract: After analysing the common random numbers(RNs)producing scheme based on John von Neumann random extraction mechanism, this paper proposes an improved effective RNs producing scheme. It just need to prepare one type of single photons and measure them, then, RNs can be get by processing the data in John von Neumann algorithm. Compared with the scheme before, this improved scheme is more concise and the photons in initial phase simplified to single photons. Furthermore, based on the statistic of RNs and error estimation, a simple method is proposed to generate unbalanced random numbers.

Key words: quantum measurement, John von Neumann algorithm, random number
