Poster presented at the 5th Conference on Quantum Information in Spain on May 28th, 2019. Rare earth ions in the solid state have excellent optical and spin coherence properties at cryogenic temperatures. They are useful for implementing quantum information applications. In particular, single REIs can be used for high-efficiency spin-photon-interfaces, and also for implementing quantum gates using dipole-dipole interactions. A challenge to interact with single ions relies however on the weak
