  Ongoing efforts in quantum engineering have recently focused on integrating
magnonics into hybrid quantum architectures for novel functionalities. While
hybrid magnon-quantum spin systems have been demonstrated with nitrogen-vacancy
(NV) centers in diamond, they have remained elusive on the technologically
promising silicon carbide (SiC) platform mainly due to difficulties in finding
a resonance overlap between the magnonic system and the spin centers. Here we
circumvent this challenge by harnessing nonlinear magnon scattering processes
in a magnetic vortex to access magnon modes that overlap in frequency with
silicon-vacancy ($\textrm{V}_{\mathrm{Si}}$) spin transitions in SiC. Our
results offer a route to develop hybrid systems that benefit from marrying the
rich nonlinear dynamics of magnons with the advantageous properties of SiC for
scalable quantum technologies.
