Abstract

An enhanced true random number generator (TRNG) architecture based on a photonic entropy source is presented. Photonic TRNGs are known to produce photon sequences at randomly distributed time intervals as well as random superimposed quantum states. We describe a TRNG architecture that takes advantage of both of these sources of entropy with a dual-source extractor function. We show that the amount of harvested entropy exceeds that compared to implementations comprised of only one of these sources. We also describe an implementation of a beam splitter used within the architecture that is suitable for implementation in a photonic integrated circuit that has been simulated and fabricated.
