Abstract
High-speed quantum random number generators (QRNGs) are of interest for a wide range of applications, including secure communication and stochastic simulation on large computers. The fastest schemes to date use homodyne detection of a coherent laser field [1] or phase diffusion in semiconductor lasers (SLs) [2,3], with bit-rates exceeding 40 Gb/s [4]. Here we demonstrate a hybrid of these techniques, and show progress toward integration into a cm-scale, multi-Gbps device.
