Claim:
1. A multiple output quantum random number generator comprising: an optical hybrid including first and second input ports to which optical source noises are respectively input, the optical hybrid configured to mix a first optical source noise input to the first input port and a second optical source noise input to the second input port and to divide a mixed optical source noise into an in-phase component and a quadrature component; a plurality of optical detectors configured to respectively convert optical source noises of in-phase components and optical source noises of quadrature components that are output from the optical hybrid into electric noises; a plurality of analog-to-digital (AD) converters configured to respectively convert electric noises output from the plurality of optical detectors to digital values; and a random number extractor, including a first channel and a second channel, configured to post-process outputs of AD converters to thereby generate two true random number sequences, and to respectively output the two random number sequences through the first and second channels.
