Here we present a new fast two-bit quantum random number generator based on the intrinsic randomness of the quantum physical phenomenon of photon statistics of coherent light source. Two-bit random numbers were generated according to the number of detected photons in each light pulse by a photon-number-resolving detector. Poissonian photon statistics of the coherent light source guaranteed the complete randomness of the bit sequences. Multi-bit true random numbers were generated for the first time based on the multi-photon events from a coherent light source.
在此，我们基于相干光源光子统计这一量子物理现象的内在随机性，提出了一种新型快速两位量子随机数发生器。通过光子数分辨探测器，根据每个光脉冲中探测到的光子数生成两位随机数。相干光源的泊松光子统计保证了比特序列的完全随机性。首次基于相干光源的多光子事件生成了多位真随机数。
