Research Abstract |
We experimentally demonstrated fast random number generation using chaotic semiconductor lasers. Chaotic fluctuation of laser output is generated and converted into binary sequences for random number generation. Statistical tests verify the randomness of bit sequences generated in the experiment. We succeeded in generating random bit sequences at rates up to 400 Gb/s. We also achieved the estimation of entropy rate and demonstrated quantum cryptography experiment with the random number generator.
