Quantum-secured network ‘virtually un-hackable’

Quantum-secured network ‘virtually un-hackable’ (New Cyber Technologies)

BT and its partners’ pipe is the first real-world, quantum-secured, high-speed network in the U.K, BT claimed in a news release. Cambridge, U.K., the site of BT’s quantum network termination, is also where the Quantum Communications Hub (a consortium of eight U.K. universities and private sector enterprises and the group working with BT) has set up a QKD-connected hub of three sites around the city, the consortium said in June. Quantum Communications claims to be able to send ultra-secure data in multiple 100 gigabit channels and to generate photon keys at speeds of two to three megabits per second. Whereas BT said its link sends data at 500 gigabits per second. Photons, as used in the quantum-key distribution work, will likely end up securing future networks and could turn out to be a crucial element to upcoming quantum computing overall. “Quantum communications technologies are starting to play a significant role in securing our data and communications," said Dr. Grégoire Ribordy, head of IDQ on a webpage related to the BT project.
