The realization of quantum networks that exploit multiqubit entanglement opens avenues for transformative applications in the realm of quantum communication. In the paper, we present a set of heralded deterministic protocols designed for the generation of two-qubit, three-qubit, and $N$-qubit Knill-Laflamme-Milburn (KLM) states by the photon scattering property in one-dimensional waveguide-emitter system. In each protocol, the auxiliary single photon functions as a universal interface to bridge all stationary qubits. Our proposed protocols allow for the conversion of irregular scattering incidents occasioned by nonideal coupling and frequency detuning into detectable events by triggering the detectors, which means that our protocols are effective for the generation of arbitrary KLM states with the predictive operational character and high fidelity. Owing to the significant breakthroughs in the integration of quantum emitters with nanophotonic waveguides, our protocols possess ideal features that position them as the promising candidates for deployment in long-range multiqubit quantum network systems.
