英国BT：与东芝共建量子密码通信网络：2021年内启动
東芝と英ＢＴ：
世界初の量子暗号通信の商用メトロネットワークを、２０２１年内をめどに構築する。
２―３年の実証期間：
その後２―３年の実証期間を設けて、英国ロンドンで複数の顧客へデータ通信サービスを試験的に提供する。
新しい通信網：
- ロンドンのドックランズと、
- シティ・オブ・ロンドン、
- 郊外Ｍ４幹線沿いの拠点を結び、
「量子鍵配送と耐量子暗号技術を使った通信サービス」を提供する。
両社はすでに２拠点間の回線を構築済みだ。
複数拠点間の量子暗号通信ネットワークは初めてという。

BT and Toshiba install UK’s first quantum-secure industrial network between key UK smart production facilities
1st October 2020, London:
BT and Toshiba Europe Limited
today announce the UK’s first industrial deployment of a quantum-secure network,
transmitting between
the National Composites Centre (NCC), the UK’s world-leading composite research
and development facility,
and the Centre for Modelling & Simulation (CFMS),
a not-for-profit research organisation that pioneers new digital engineering capabilities.
Funded by Innovate UK’s AQuaSeC project,
the network demonstrates how Quantum Key Distribution (QKD)
– an essentially un-hackable, cutting edge technique for sharing encryption ‘keys’ between locations using a stream of single photons –
can be used to secure data traffic between key industrial sites where security is of paramount importance.
Using standard Openreach fibre, Toshiba’s QKD system enables the distribution of 1000s of cryptographic keys per second.
Its innovative multiplexing compatibility
allows the data and the quantum keys to be transmitted on the same fibre, eliminating the need for costly dedicated infrastructure for key distribution.
While this first deployment covers a range of 6km, the current maximum range extends up to 120km – allowing ultra-secure data transmission across major metropolitan environments.
