BT bolsters research in quantum technologies

BT is increasing its investment in quantum technologies. “We have a whole team of people doing quantum and it is growing really fast,” says Andrew Lord, head of optical communications at BT.

The UK incumbent is working with companies such as Huawei, ADVA Optical Networking and ID Quantique on quantum cryptography, used for secure point-to-point communications. And in February, BT joined the Telecom Infra Project (TIP), and will work with Facebook and other TIP members at BT Labs in Adastral Park and at London’s Tech City. Quantum computing is one early project.

Andrew LordThe topics of quantum computing and data security are linked. The advent of quantum computers promises the break the encryption schemes securing data today, while developments in quantum cryptography coupled with advances in mathematics promise new schemes resilient to the quantum computer threat.

Books of the year 2016 - Part 1

Each year Gazettabyte asks industry figures to comment on books that they recommend. Here are BT's Andrew Lord's and Cignal's Andrew Schmitt's recommendations to kick off this year's reviews.


Andrew Lord, Head of Optical Research at BT.

Quantum technologies are flavour of the month, with huge government investments from around the world. The title and cover of Bananaworld: Quantum Mechanics for Primates by Jeffrey Bub, suggest a book that will ‘unpeel’ a tough but increasingly important subject for general readers. 

The book itself is, however, far deeper than its cover suggests, going way beyond the basics, and attempting to forge a link between quantum mechanics and the structure of information.

BT makes plans for continued traffic growth in its core 

Briefing: DWDM developments

Part 1

Kevin Smith: “A lot of the work we are doing with the trials have demonstrated we can scale our networks gracefully rather than there being a brick wall of a problem.”

BT is confident that its core network will accommodate the expected IP traffic growth over the next decade. Traffic in BT’s core is growing at between 35 and 40 percent annually, compared to the global average growth rate of 20 to 30 percent. BT attributes its higher growth to the rollout of fibre-based broadband across the UK.

The telco is deploying 100-gigabit wavelengths in high-traffic areas of its network. “These are key sites where we're running out of wavelengths such that we need to implement higher-speed ones,” says Kevin Smith, research leader for BT’s transport networks. The operator is now trialling 200-gigabit wavelengths using polarisation multiplexing, 16-quadrature amplitude modulation (PM-16QAM).
