  Quantum communication promises unprecedented communication capabilities
enabled by the transmission of quantum states of light. However, current
implementations face severe limitations in communication distance due to photon
loss. Silicon carbide (SiC) defects have emerged as a promising quantum device
platform, offering strong optical transitions, long spin coherence lifetimes
and the opportunity for integration with semiconductor devices. Some defects
with optical transitions in the telecom range have been identified, allowing to
interface with fiber networks without the need for wavelength conversion. These
unique properties make SiC an attractive platform for the implementation of
quantum nodes for quantum communication networks. We provide an overview of the
most prominent defects in SiC and their implementation in spin-photon
interfaces. Furthermore, we model a memory-enhanced quantum communication
protocol in order to extract the parameters required to surpass a direct
point-to-point link performance. Based on these insights, we summarize the key
steps required towards the deployment of SiC devices in large-scale quantum
communication networks.
