Abstract: The disclosed embodiments generally use multiple QRNGs contained within independent servers operating in a round-robin fashion via an Application Programming Interface (API) such that the quality of the random number bitstream can be enhanced due to a sum of entropy being gathered across multiple QRNGs that are multiplicative in nature. This allows for multiple modes of operation to be accomplished, the first being a higher overall random stream bitrate, the second being an enhanced entropy stream where output from the independent QRNGs are interleaved together to improve the quality of the random bitstream, and the third mode of operation where a minimum guaranteed random bitstream rate is maintained equal to the redundancy value chosen by the operator based upon the quantity of QRNG devices within the system.
