1. A system for generating clock signals for a photonic quantum computing system, the system comprising:
a pump photon source configured to generate a plurality of pump photon pulses at a first repetition rate;
a photon-pair source optically coupled to the pump photon source, the photon-pair source configured to:
convert a subset of the plurality of pump photon pulses into photon pairs;
output the photon pairs; and
output a portion of each pump photon pulse of the plurality of pump photon pulses;
a photodetector optically coupled to the photon-pair source and configured to:
receive the portion of each pump photon pulse of the plurality of pump photon pulses; and
converting the portion of each pump photon pulse of the plurality of pump photon pulses into a respective electrical pulse of a plurality of electrical pulses; and
a clock generator electrically coupled to the photodetector and configured to convert the plurality of electrical pulses into a plurality of clock signals at the first repetition rate.
