Quantum entropy model of an integrated QRNG chip
arXiv:2011.14129 · doi:10.1103/PhysRevApplied.15.054048
Abstract
We present the physical model for the entropy source of a quantum random number generator chip based on the quantum fluctuations of the photon number emitted by light-emitting diodes. This model, combined with a characterization of the chip, estimates a quantum min-entropy of over 0.98 per bit without post-processing. Finally, we show with our model that the performances in terms of security are robust against fluctuations over time.
