Telefónica, Huawei, and UPM (Universidad Politécnica de Madrid) have performed a groundbreaking field trial, the first one worldwide, demonstrating the application of quantum cryptography on commercial optical networks, and their operational integration by means of Software Defined Networking (SDN) technologies.
It is an advanced research pilot of secure communication services based on quantum technologies that Telefonica could provide to its customers in future. As Juan-Ignacio Cirac, distinguished physicist specialized in quantum computing and member of the Telefónica Board, says: “We can make a random bit sequence to appear at one place and simultaneously at another one, without making it pass in between. It is sort of magic, but something that Quantum Physics predicts. It is a way of exchanging secure keys that we have to make the most of, since it cannot be hacked”.
