BT Is Using Quantum Technology To Secure Gigabytes Of Sensitive Data Sent Between Two Industrial Sites In The UK

Did the promise of quantum-secure networking just take an important this is not hype leap?

Things are certainly looking promising with the news that telecom giant BT and Toshiba Labs have hooked up two research sites in the UK city of Bristol over a 6km link using Quantum Key Distribution (QKD).

The sites are National Composites Centre (NCC) at the University of Bristol, a development center researching the manufacture of composite materials, and the Centre for Modelling & Simulation (CFMS), which carries out engineering testing.

This might like just another demo of the emerging use of quantum and QKD technology, but there’s an important twist – the link is used to transfer large amounts of data on an ongoing basis, making this one of the first mainstream uses of QKD for that purpose yet made public anywhere in the world.
