Quantum Algorithms Outlook 2022

In contrast to the hype, the early applications of quantum computers look modest. But they do exist. The talented teams developing quantum algorithms still have a fight on their hands to bring forward the date of true broad quantum advantage. What might be achieved and when?

Quantum safe cryptography – the big picture

Recently updated advice on quantum security technologies from the UK NCSC is bluntly sceptical about the promised benefits of quantum key distribution. This seems at odds with the scramble of governments around the world to promote the development of quantum networking technologies. Who is right? Future large scale quantum computers will one day bring many…

Quantum Software - over-hyped but underestimated

Quantum software – over-hyped but underestimated

The advantages a quantum computer can offer depend on the quantum algorithms it can run and also how easily we can get data in and out of the system. Today’s hardware is still well short of the universal quantum dream and, in truth, the most often discussed benefits are still many years away. However the…

Introduction to Quantum Information Processing

Quantum computers offer no advantage in and of themselves. Their true potential is only realised when they run new quantum algorithms. Conventional computers have benefited from 50 years of continuous development. The speed of their underlying logic gate operations will be significantly faster than the speed of quantum gate operations for the foreseeable future. Take…
