摘要: A quantum random number generator (QRNG) based on a silicon nanocrystals (Si-NCs) light emitting device (LED) coupled with single photon avalanche photodiode (Si-SPAD) is presented. simple setup used for the generation of bits. The modeled approach assures negligible bias datasets ∼100 Mbits length. raw data pass all statistical tests in National Institute Standards and Technology (NIST) suite without any post-processing operations. bit-rate 0.6 Mbps achieved. information-theoretically provable randomness extractor Toeplitz-hashing function applied to longer (∼1 Gbits) extract randomness, minimize bias, consequently NIST tests. Stabilizing temperature, resetting current LED, or feedback system can also be as parameter control solutions generate good quality, long numbers suitable cryptographic applications.
