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…
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…
In 2020 everyone will want to persuade you to join their quantum software camp. Not everyone will come away happy. Huddling round the community fire may be a good way to keep the chills of quantum winter at bay. Making camp Everyone knows how lucrative controlling the software playing field became in the original Digital…
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…
