Zusammenfassung: | 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. |
