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... Read more

Superconducting qubits have seized an early lead in commercial quantum computing activity. Being first to demonstrate technical quantum supremacy means they are well placed to search for NISQ quantum advantage. However there are significant challenges to be faced in scaling up these systems in the extreme cryogenic environments they require.... Read more

Years of academic activity is now transforming itself into a wave of spin-outs and startups. Trapped ion proponents point to the very high fidelity gates that have been achieved and additional opportunities for qubit connectivity. However the best gates have historically required precision Raman laser setups that come with their... Read more
