  Quantum communication is at the forefront of quantum technology, enabling the
development of absolutely secure encryption, distributed quantum computing,
teleportation and more. Whilst quantum communication has been experimentally
demonstrated at distances on the order of hundreds of kilometers, the
establishment of high-fidelity pairs shared over larger distances remains a
formidable technical challenge due to attenuation. However, this may be
overcome with the use of quantum repeaters. Here we propose a method to
construct a robust quantum repeater network using only existing technology. Our
protocol is able to perform all parts of the procedure in a way that is highly
tolerant to photon loss and imperfections in detectors, and it achieves secure
bit rates on the order of kilohertz over intercontinental distances.
