Quantum Software Stack

Quantum Software Stack – a brief overview

Since the birth of modern computing, progress has been supported by the evolution of an evermore sophisticated layered approach to software. A wide variety of majors and startups are vying to secure their place in the quantum software sector. To understand their plans we have to ask both what is similar and what is different…

Quantum Hardware Outlook 2021

Quantum Hardware Outlook 2021

China’s quantum supremacy demonstration may grab headlines, but not yet leadership in the quantum computing race. Leading hardware groups have firmed-up their development roadmaps for the marathon ahead and error correction has become a key part of the story. The challenge of scaling-up remains pre-eminent. A growing number of quantum majors, startups and institutes are…

Quantum software – beneath the quantum hype

Commercial activity around quantum computing has risen to fever pitch over the last year. Many point to the traditional cycle of hype and consolidation in tech markets. Some have become quick to call ‘bullshit’ much of the activity at the current commercial frontier. Others predict a coming quantum winter. How can investors and early adopters…

Quantum Error Correction - from 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

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 computing race

Qubit technology: global field microwave trapped ions

Are quantum majors Google, IBM, Intel and Alibaba backing the right technologies for the long term? Quantum majors Google, IBM, Intel and Alibaba, together with startup Rigetti have so far focussed on building quantum devices based on superconducting qubits. Many expect that quantum supremacy will soon be demonstrated based on such a device. But how…

Quantum Computing marathon

Jury out on which platform will ultimately win the quantum computing marathon

Articles in the popular press have given competing experimentalists the opportunity for some polite scientific knocking copy A series of recent articles across the New Scientist, Financial Times and Bloomberg quote leading experimental groups, and give insight into the state of reality and hype in the nascent quantum computing sector. Different scientific groups have spent years…

Quantum Computers

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…

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.
