Quantum safe cryptography – waiting to save the world

Future quantum computers will one day bring us many great benefits. Unfortunately they will also break many of the cryptographic protocols on which current Internet security depends. Google’s quantum supremacy breakthrough notwithstanding, this is still most likely many years off. However, sensitive data intercepted and stored today, or long lifecycle infrastructure could already be at…

Quantum supremacy – a new era?

Google has achieved quantum supremacy – the ability to perform a calculation beyond the reach of conventional computers. This is a landmark scientific, mathematical and technical achievement. Though the road to general purpose quantum computing remains a long one, early applications will surprise many. Google had planned to announce quantum supremacy through a paper in…

Quantum Blockchain

Quantum enhanced blockchain – sooner than you think?

Future quantum computers will ultimately force blockchain solutions to adopt strengthened quantum safe crypto protocols. Rationally there remains plenty of time to act, but proponents need to get their transition stories in place to avoid being caught out as we near peak quantum hype. More positively, the nascent blockchain industry also stands to be among…

Quantum Technology for a Global Britain?

The UK Quantum Showcase demonstrates why others around the world are seeking to copy the UK’s quantum technology approach. It’s little surprise that the UK government is providing additional funding of £315m over the next 5 years. The 2018 UK National Quantum Technology Showcase took place in the prestigious QEII conference centre overlooking London’s Parliament…

The central role of quantum software

Quantum thought leader Scott Aaronson reminds us that the challenge of achieving quantum advantage depends not just on breakthrough quantum hardware but also on mastering revolutionary new quantum software. Scott Aaronson is a professor of Computer Science at the University of Texas at Austin, and the founding director of its Quantum Information Center. An expert…


Quantum attacks on Bitcoin and how to protect against them

Academics argue that Bitcoin could be subject to attack from quantum computers by 2027. There are plenty of ways to meet this challenge, but given recent experience how easy will the Bitcoin community find it to organise its response? A new paper from Aggarwal, Brennen, Lee et al. starts by underlining the strength of Bitcoin’s main…

Introduction to Quantum Safe Cryptography

Commercial transactions on the Internet and routine cyber security depend on the effectiveness of public key cryptography. Quantum computers will make existing standards obsolete. The impact of this starts now. The central technical pillar of online security is the use of secure cryptographic algorithms to encrypt data, passwords and identities, and so keep them safe…
