  A solid-state approach for quantum networks is advantages, as it allows the
integration of nanophotonics to enhance the photon emission and the utilization
of weakly coupled nuclear spins for long-lived storage. Silicon carbide,
specifically point defects within it, shows great promise in this regard due to
the easy of availability and well-established nanofabrication techniques.
Despite of remarkable progresses made, achieving spin-photon entanglement
remains a crucial aspect to be realized. In this paper, we experimentally
generate entanglement between a silicon vacancy defect in silicon carbide and a
scattered single photon in the zero-phonon line. The spin state is measured by
detecting photons scattered in the phonon sideband. The photonic qubit is
encoded in the time-bin degree-of-freedom and measured using an unbalanced
Mach-Zehnder interferometer. Photonic correlations not only reveal the quality
of the entanglement but also verify the deterministic nature of the
entanglement creation process. By harnessing two pairs of such spin-photon
entanglement, it becomes straightforward to entangle remote quantum nodes at
long distance.
