Quantum networks promise to enable applications ranging from secure communication to fundamentally new kinds of computation. However, the individual components of quantum networks may be realized with different kinds of physical systems, requiring specialized interfaces. Here we present our work towards interfacing a diamond Nitrogen Vacancy (NV) center, well suited as a local quantum processing network node [1], with light compatible with Tm-based rare-earth ion quantum memories, well suited for long-range quantum repeaters [2]. We demonstrate two-photon quantum interference between photons emitted from an NV center with weak coherent light resonant with a Tm-based memory, probing the indistinguishability of the photons created by these disparate sources, using a low noise two-step quantum frequency conversion process. Furthermore, we present latest results towards teleporting a memory-compatible time-bin qubits into the NV center. With this quantum interface between different physical systems, we aim to bridge the gap between two key network components. [1] Hermans, S.L.N. et al. Nature 605 (2022) [2] Davidson J.H. et al.
