The efficient unidirectional routing of photonic qubits is significant in the fields of both classical and quantum information processing. However, the photonic qubit router is still elusive due to the simultaneous requirements for high fidelity, precise directionality, and high isolation ratio. Here, we introduce a method to achieve non-Hermitian unidirectional routing of photonic qubits. Our method leverages tunable incoherent dissipative channels connecting traveling photonic qubits with localized atomic systems. Through dynamic control of both coherent and incoherent channels via manipulation of the control field’s helicity, we clarify the transition from nondirectional to unidirectional routing. The experimental results showcase the qubit fidelity exceeding 97.49% and the isolation ratio surpassing 14dB. This method not only enables the establishment of extensive quantum networks but also serves as a pivotal component in chiral topological photonics, chiral networks, and unidirectional quantum information transfer.
