Is Quantum Secured Metro Network the future of Secure Communication


BT and Toshiba have joined hands to launch the world’s 1st quantum secured metro network (QSMN) that is hard to hack say experts. This secure mode of network was launched early this week across London and aims to offer internet users a secure transmission mode for their valuable data- all via the fiber optic cable and led by Quantum Key Distribution (QKD).

The whole setup of secure communication using quantum technology was supposed to be launched in September 2021. However, it witnessed a delay of almost 8 months and was finally rolled out on April 25th, 2022.

Initially, the new technology will connect two office sites of EY in Canary Wharf and London Bridge and BT have been assigned with the duty to operate and maintain the network.

A dedicated bandwidth connecting end-to-end encrypted links will secure the Openreach’s fiber network. Toshiba will provide QKD Hardware and Key Management Software useful to build Ethernet security.

Testing of quantum secured metro network services was done in November 2021 and all needed equipment such as racks and optimization of network was done by February this year.

As per the UK Government Strategic digital development plan, the next 10 years will prove crucial to the Internet as hackers will be seen launching cyber attacks using the technology of quantum computing.

So, British Telecom (BT) in association with Ernest Young(EY) and Toshiba are planning to unlock an innovation that will offer a secure mode of web communication using the quantum science and technology department.
