TY  - JOUR
AB  - We investigate the generation of random numbers via the quantum process of spontaneous Ramanscattering. Spontaneous Raman photons are produced by illuminating a highly nonlinearchalcogenide glass (As2S3) fiber with a CW laser at a power well below the stimulated Ramanthreshold. Single Raman photons are collected and separated into two discrete wavelengthdetuning bins of equal scattering probability. The sequence of photon detection clicks is convertedinto a random bit stream. Postprocessing is applied to remove detector bias, resulting in a final bitrate of 650 kb/s. The collected random bit-sequences pass the NIST statistical test suite for onehundred 1 Mb samples, with the significance level set to a ¼ 0:01. The fiber is stable, robust andthe high nonlinearity (compared to silica) allows for a short fiber length and low pump powerfavourable for real world application.
