Abstract: A system for generating a quantum random number stream may include a first noise source. The system may also include a first bias device, configured to bias the first noise source such that the first noise source generates a first noise, and a second noise source and a second bias device, configured to bias the second noise source such that the second noise source generates a second noise. The system may also include a first amplifier with a first input channel and a second input channel configured to receive the first noise and the second noise, respectively. The amplifier may use a difference between the first and second noises to generate a first amplified analog signal for output. The system may also include an analog-to-digital converter device configured to convert an amplified analog signal to the quantum random number stream then output the quantum random number stream.

Abstract: A system for securely moving data from one location to another exchanges key material between the locations. The system enables cryptosystems to use key material distributed over a quantum channel.
