Query: 502 Gbits/s Quantum Random Number Generation with Simple and Compact
  Structure   We propose and implement a simple and compact quantum random number
generation (QRNG) scheme based on the quantum phase fluctuations of a DFB
laser. The distribution probability of the experimentally measured data fits
well with the simulation result, got from the theoretical model we established.
Min-entropy estimation and Toeplitz-hashing randomness extractor are used to
obtain the final random bit. The proposed approach has advantages not only in
simple structure but also in high random bit generation rate. As a result, 502
Gbits/s random bits generation speed can be obtained, which is much higher than
previous similar schemes. This approach offers a possibility to promote the
practical application of QRNG.
