Abstract
In this thesis, we explore the fabrication methods aimed at engineering integrated spin-photon interfaces based on SnV centers in diamond nanostructures for future quantum networks. We first introduce the group-IV color centers, elaborating on their spin and optical properties as future quantum networks end-node candidates. Specifically, the inversion symmetry of these color centers opens the path towards nanophotonic integration, a key step to enable scalability. However, integration of tin-vacancy (SnV) color centers in diamond and fabrication of suspended nanophotonic devices is challenging....
