Quantum Hardware Outlook 2022

Big ticket investments have created a growing number of quantum unicorns. Chinese strides with photonic and superconducting qubits have grabbed attention. Trapped ions have shone with demonstrations of logical qubits. But who is winning the race to build a practical quantum computer?

Quantum Hardware Platforms – a brief overview

To understand the ambitious roadmaps of quantum hardware players we have to start by understand the contrasting advantages and challenges of each of their technology platforms. As we seek to scale up these solutions, the specific flavour of the technology being employed becomes increasingly important. This overview is taken from a presentation originally delivered at…

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 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…
