1. A single-photon Raman optical frequency comb source, comprising:
a light source assembly configured to generate a Raman scattering light;
a filtering mechanism configured to pass a light having a specific wavelength, so as to filter the Raman scattering light and obtain at least three Raman scattering spectral lines;
at least three electro-optical modulators, wherein each electro-optical modulator is configured to modulate a frequency of one Raman scattering spectrum line of the at least three Raman scattering spectrum lines in one-to-one correspondence, so as to cause a frequency shift of the Raman scattering spectrum line;
a wavelength division multiplexer configured to multiplex all modulated Raman scattering spectral lines and output a Raman optical frequency comb; and
a single photon generating mechanism configured to adjust the Raman optical frequency comb to obtain a single-photon Raman optical frequency comb.
