1. A vacuum fluctuation quantum random number generator chip comprising:
a heat sink substrate;
a laser fixed to a first end of the heat sink substrate;
at least two photoelectric detectors fixed to a second end of the heat sink substrate; and
a beam splitter fixed to the heat sink substrate and located between the laser and the at least two photoelectric detectors;
wherein:
light of the laser propagates through the beam splitter;
the at least two photoelectric detectors are respectively positioned at optical path outlets of the beam splitter; and
an emission end of the beam splitter includes a bevel structure having an angle less than 90°.
