摘　　要：We experimentally demonstrate a kind of high-quantum correlated,practical quantum random generation based on the quantum phase noise of a laser,which uniformly distributes in the range of(-π,π]by driving the laser with a stream of narrow electrical pulses.We propose a working mode to further suppress the impact of phase drift after we use the passive measures(thermal and mechanical isolation)to slow it down.Moreover,a new method which ensures random numbers to be true representations of quantum characteristics is presented to quantify the quantum randomness.This scheme has an inherent advantage for multiplex generation.
