The future quantum internet will consist of different functionalities that are connect quantum mechanically over long distances. Here we demonstrate an important step towards such a hybrid quantum network. We have achieve a telecom single photon link between an atomic source and a solid state memory. Importantly we show that the two nodes have very different functionalities: the source is capable of generating high-quality single photons and the solid-state memory can store these photons in mutliple temporal modes with high efficiencies. Our two nodes operate at telecom wavelengths which enables long-distance deployment which we did across Hydepark.
