Abstract

Considering imperfect experimental conditions, here we give a practical proposal on the decoy-state quantum random number generator with weak coherent sources. In the proposal, three different intensities of light sources are used to estimate the contribution of single-photon pulses. System randomness is characterized and simulated through the minimum entropy. Numerical simulation results show that our new scheme can extract out randomness close to the asymptotic case where the fraction of single-photon pulses are exactly known. Furthermore, a proof-of-principle experimental demonstration is presented, showing excellent agreement between experiment and theory.
