Interested in a single material platform for quantum network components that require light-matter interaction? After having worked for almost two decades with ensembles of rare-earth ions with the goal to create quantum memories for light, we have recently extended our activities towards individual ions. If you want to learn about Frequency Tunable, Cavity-Enhanced Single Erbium Quantum Emitter in the Telecom Band, have a look at our latest paper. Thanks a lot to Simon Gröblacher and his team at TU Delft for this great collaborative effort!
