Entangling single atoms over 33 km telecom fibre.

ABSTRACT: Quantum networks promise to provide the infrastructure for many disruptive applications, such as efficient long-distance quantum communication and distributed quantum computing^1,2. Central to these networks is the ability to distribute entanglement between distant nodes using photonic channels. Initially developed for quantum teleportation^3,4 and loophole-free tests of Bell's inequality^5,6, recently, entanglement distribution has also been achieved over telecom fibres and analysed retrospectively^7,8. Yet, to fully use entanglement over long-distance quantum network links it is mandatory to know it is available at the nodes before the entangled state decays. Here we demonstrate heralded entanglement between two independently trapped single rubidiu
