In this talk we explore the dynamics of a single 171Yb ion interacting with a small, local ensemble of vanadium lattice spins. We propose using collective modes of this ensemble (nuclear magnons) as a quantum register, a key resource for building quantum repeaters. The two main challenges associated with this approach are polarising the local V spin environment and engineering coherent swap interactions between the Yb and V spins. We present experimental results characterising the Yb--V interaction.
