英文摘要	we demonstrate a novel high speed and multi-bit optical quantum random number generator by continuously measuring arrival time of photons with a common starting point. to obtain the unbiased and post-processing free random bits, the measured photon arrival time is converted into the sum of integral multiple of a fixed period and a phase time. theoretical and experimental results show that the phase time is an independent and uniform random variable. a random bit extraction method by encoding the phase time is proposed. an experimental setup has been built and the unbiased random bit generation rate could reach 128 mb/s, with random bit generation efficiency of 8 bits per detected photon. the random numbers passed all tests in the statistical test suite.
