Abstract Efficiently routing the quantum signals between different channels is essential in a quantum multichannel network. We investigate the quantum routing in a multi-cross-shaped waveguide coupled to driven three-level systems. Numerical results show that the high routing capacity transferring from the input channel to the other channels can be explicitly enhanced by effective reflection potentials. The proposed system may be utilized as a scalable quantum device to control single-photon routing.
