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…
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…
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 own significant challenges. Strip away…
