An important aspect of any QRNG is the speed of the system. This paper introduces the theory behind a pseudothermal light based QRNG. This pseudothermal effect is provided by using an optical scatterer in the setup. Pseudothermal light is used as the local oscillator of the system instead of a conventional coherent or thermal light source where the pseudothermal light combines the advantages of both sources. This technique converts the Poissonian distribution of light to super-Poissonian to have better randomness characteristics and allow a faster bit generation rate.engrestrictedAccessconferenceObject10.1109/ISMSIT50672.2020.9254508Quantum random number generatorPseudothermal lightScatteringPhoton statisticsPoisson distribution2-s2.0-85097683787
