Abstract：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.
