Abstract: The benchmark for a global quantum internet — quantum teleportation of independent qubits using active feed-forward over a free-space link whose attenuation corresponds to the path between a satellite and a ground station — has now been successfully achieved over a distance of 143 km, between the Canary Islands of La Palma and Tenerife.
