Experimental demonstration of high-entropy time of arrival based optical QRNG qualifying stringent statistical tests
Abstract
We report a demonstration of a high-entropy optical quantum random number generator (QRNG) based on photon arrival time. We have implemented the scheme with high-speed and high-precision electronics with a time resolution of 1 ps generating 115 Mbps raw data. The random bit generation efficiency is 8 bits per detection. The experimental data is quite consistent with theoretical estimation showing minimum bias. We apply a real-time information-theoretic randomness extractor to generate a final data rate of 109 Mbps. The randomness is rigorously evaluated against well-known statistical test suites of NIST, ENT, Diehard, TU-01 and Dieharder.
