In stochastic computation, one of the probabilistic computation methods, it is well known that the computational accuracy deteriorates when the input stochastic numbers are correlated. We have proposed a stochastic number splitter in which frequency synchronisation in a single flux quantum circuit is applied to superconducting random number generators connected in parallel. In this study, we have designed, fabricated and evaluated this four-fan-out stochastic number splitter. We have demonstrated its high-speed operation.
