We investigate a quantum random number generation (QRNG) based on backward spontaneous Raman scattering (SpRS) in standard single-mode fiber, where the randomness of photon wavelength superposition and arrival time are simultaneously utilized. The experiment uses four avalanche photodiodes working in gated Geiger mode to detect backward Raman scattering photons from four different wavelength channels and a time-to-digital converter placed behind the detectors to record their arrival time.
