Heralded entanglement between distant quantum memories is the key resourcefor quantum networks. Based on quantum repeater protocols, these networks willfacilitate efficient large-scale quantum communication and distributed quantumcomputing. However, despite vast efforts, long-distance fibre based networklinks have not been realized yet. Here we present results demonstratingheralded entanglement between two independent, remote single-atom quantummemories generated over fibre links with a total length up to 33 km. Toovercome the attenuation losses in the long optical fibres of photons initiallyemitted by the Rubidium quantum memories, we employ polarization-preservingquantum frequency conversion to the low loss telecom band. The presented workrepresents a milestone towards the realization of efficient quantum networklinks.
