【TOSHIBA】Quantum Key Distribution Use Case with BT, NCC & CFMS
British BT: To build quantum cryptography communication network with Toshiba: Start within 2021
Toshiba and British BT:
The world’s first commercial metro network for quantum cryptography will be built by 2021.
2-3 year demonstration period:
After that, a demonstration period of 2-3 years will be set, and data communication services will be provided on a trial basis to multiple customers in London, England.
New communication network:
With the Docklands in London,
City of London,
Connecting bases along the suburban M4 trunk line,
We provide “communication service using quantum key distribution and quantum cryptography technology”.
Both companies have already built a line between the two bases.
It is said that this is the first quantum cryptography communication network between multiple bases.
New switch
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.
