BT adds quantum security to hollowcore fibre

BT is pretty upbeat about the possibilities of using quantum security methods to transmit data over hollowcore fibre, carrying out a trial that has implications for faster, less hackable connections.
The UK incumbent is building on previous endeavours in both hollowcore fibre and quantum security, specifically, Quantum Key Distribution (QKD). It has trialled QKD over hollowcore fibre and is claiming a world first for having done so.
“This is an exciting milestone for BT, accelerating the U
