Spin-photon interfaces augmented with auxiliary qubits are prime candidates for quantum repeater nodes. I will present our theoretical work toward the realization of practical quantum repeaters, focusing on the triggered generation of highly entangled photonic (graph) states from a spin-photon interface and their performance-resource tradeoff in a network. I will also discuss our quantum control work on the selective high-fidelity control of a nuclear spin register coupled to an NV center spin in diamond.
