Quantum supremacy

Quantum supremacy – a new era?

Google claims quantum supremacy – the ability to perform a calculation beyond the reach of conventional computers. This is a landmark scientific, mathematical and technical achievement. But as many such as IBM point out we should all beware of hype. The road to general purpose quantum computing remains a long one. Google has published a…

Quantum error correction - geek to superhero

Quantum error correction – from geek to superhero

Quantum computers can only realise their full potential by defeating the noise that plagues their delicate qubits. The field of quantum error correction offers some increasingly mature solutions. But it is also still a rapidly evolving discipline, and innovation here, as much as in hardware, will shape the future quantum computing roadmap. If 50-70 qubits are…

Introduction to fault tolerant quantum computation

Right from the conception of quantum computers it was realised that controlling the build-up of errors in quantum computations is a key problem. Theoretical progress over the last 25 years has led to the development of techniques ready to meet this challenge. This introduction is for readers interested in the terminology of quantum error correcting…

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…

Quantum Europe

Europe’s drive to create wealth from Quantum Technology

The focus of the EU’s €1b Quantum Flagship programme is not basic science, nor is it simply about bringing new technologies to market. The end-goal is driving wealth creation, jobs and societal benefits in Europe. This requires kick-starting the competitive position of European industry in this sector and making Europe the region of choice for…

Quantum Strategy

Quantum strategies in the NISQ era

We are about to enter a new transitional phase in the development of quantum technology. Behind the headlines there are a diversity of strategies available for those wanting to get on board. In 2012 Caltech professor John Preskill coined the term quantum supremacy for the quest to demonstrate a calculation on a quantum device that…

Quantum hardware in the NISQ era

Excitement mounts as we approach a demonstration of quantum supremacy. However a very long road remains to build a fault tolerant quantum computer Quantum hardware announcements continue to come at speed: Google has just announced Bristlecone, a 72 superconducting qubit device (though it remains to be seen if it can maintain the high fidelity performance of its…

Introduction to Quantum Computers

An immediate challenge for the interested business observer is how to interpret the true state of progress against a background of hype and corporate spin. All conventional computing is ultimately based on data stored as digital bits, each a 1 or 0, and their manipulation via logic gates. The great power of modern computing comes…

Introduction to Quantum Technology Terminology

A new wave of technology is set to take the world beyond binary 1 and 0. Revolutions 1QR The advent of quantum mechanics and its many experimental confirmations during the 20th century was by most measures the greatest revolution in the physical sciences since Copernicus put the sun at the centre of the solar system.…

The Second Quantum Revolution - Actions for Business

The Second Quantum Revolution – Actions for Business

A new wave of technology is set to take the world beyond binary 1 and 0. The post-digital era will bring transformational opportunities in many areas of business. Forward looking companies need to act to seize the possibilities and avoid the risks of this new order.
