Quantum hardware – into the quantum jungle

The quantum computing landscape has been transformed by a surge of commercial startups pursuing very different technical paths. Investors and pioneers must prepare themselves for a challenging journey ahead. A growing list of major, midsized and startup companies have joined the quantum computing quest. However today’s prototype devices must be radically scaled up before they…

Topological qubits

Topological qubits

We don’t worry about errors in conventional computing chips because the digital transistor has hardware error correction built in. That’s why transistors replaced valves, unlocking the digital revolution. The idea behind topological qubits is to repeat this trick. Topological qubit proponents often use the analogy of tying a knot in a piece of string. The…

Quantum Hardware Outlook

Quantum Hardware Outlook 2020

2019 saw Google finally demonstrate quantum supremacy. Competitors such as IBM reminded us that this was just an opening skirmish in what will be a long campaign. In 2020 we will see paths divide as competing companies and technologies face-up to the quantum chasm blocking the way to large scale quantum computers. The hard road…

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 Outlook

Quantum Outlook 2019

2018 has seen rising awareness of the future potential of quantum technology. 2019 is set to see quantum computing in particular at the peak of its hype cycle. Fact Based Insight believes that investors should take a wide view of the sector to find value in the short, medium and long term. The road to…

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…
