A quantum telecommunications network includes nodes, typically on the ground; a conventional telecommunications network connecting the nodes to one another; and at least one satellite or airborne carrier able to generate and transmit multiplets of entangled photons to the nodes. The nodes are configured to collect photons from the satellite, take joint quantum measurements and exchange conventional information with other nodes via the conventional telecommunications network. Node and satellite payload for such a quantum telecommunications network. Method for quantum telecommunications by way of such a network.
