Single-photon quantum router with multiple output ports

Understand

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.
