The tin-vacancy centre in diamond (SnV) has very recently attracted increasing interest as a promising system for quantum information protocols, as a candidate which may offer both the optical as well as the spin coherence properties needed for a robust spin-photon interface in a quantum node. Motivated by this, we present our progress towards investigating the feasibility of deploying the SnV for the generation of resource states for quantum communication protocols. First and foremost, this necessitates the ability to reliably generate and control single SnVs with the required properties. In this work, we therefore focus upon the characterisation of optical and spin coherence properties of SnVs, which are artificially generated with differing implantation strategies and integrated into diamond nanopillars. This enables a route to optimise the yield of nanopillar integrated single SnVs, and therefore provides a means to realise a scalable spin-photon quantum node.
