A quantum leap in fear

The advent of quantum computing poses a threat which could break open the security systems protecting the world’s financial data and transactions. 

Professor Michele Mosca

Protecting financial data has always been a cat-and-mouse game. What is different now is that the cat could be de-clawed. Quantum computing, a new form of computer processing, promises to break open the security systems that safeguard much of the world’s financial data and transactions.

Quantum computing is expected to be much more powerful than anything currently available because it does not rely on the binary digits 1 or 0 to represent data but exploits the fact that subatomic particles can exist in more than one state at once.

Experts cannot say with certainty when a fully-fledged quantum computer will exist but, once it does, public key encryption schemes in use today will be breakable. Quantum computer algorithms that can crack such schemes have already been put through their paces.

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.

IoT will drive chip design and new styles of computing

Looking back 20 years hence, how will this period be viewed? The question was posed by the CEO of imec, Luc Van de hove, during his opening talk at a day event imec organised in Tel-Aviv.

For Van den hove, this period will be seen as one of turbulent technological change. “The world is changing at an incredible rate,” he says. “The era of digital disruption is changing our industry and this disruption is not going to stop.”

It was the Belgium nonoelectronics R&D centre’s second visit to Israel to promote its chip and systems expertise as it seeks to expand its links with Israel’s high-tech industry. And what most excites imec is the Internet of Things (IoT), the advent of connected smart devices that turn data into information and adapt the environment to our needs.

Intelligent networking: Q&A with Alcatel-Lucent's CTO

Alcatel-Lucent's corporate CTO, Marcus Weldon, in a Q&A with Gazettabyte. Here, in Part 1, he talks about the future of the network, why developing in-house ASICs is important and why Bell Labs is researching quantum computing.
