  We study the multi-channel quantum routing of the single photons in a
waveguide-emitter system. The channels are composed by the waveguides and are
connected by intermediate two-level emitters. By adjusting the intermediate
emitters, the output channels of the input single photons can be controlled.
This is demonstrated for the cases of one output channel, two output channels
and the generic N output channels. The results show that the multi-channel
quantum routing of single photons can be well achieved in present system. This
sheds light on the experimental realization of quantum routing of single
photons.
