Abstract Silicon-carbide (SiC) is a promising platform for long-distance quantum information transmission via single photons, offering long spin coherence qubits, excellent electronic and optical characteristics and CMOS-compatibility. We review key properties of spin-photon interface components for future deployment on the SiC-on-insulator platform with detailed insights provided for available color centers as well as integrated photonic circuits. The associated challenges to achieve high-fidelity multi-qubit control and photon-mediated entanglement on-chip are elaborated, perspectively.
