In contrast to the hype, the early applications of quantum computers look modest. But they do exist. The talented teams developing quantum algorithms still have a fight on their hands to bring forward the date of true broad quantum advantage. What might be achieved and when?
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?
The cyber world is embattled. Can a new quantum unicorn ride to the rescue? A novel solution is seeking to harness the power of three deep tech disciplines – quantum, crypto and space. What are the strengths and weaknesses of this new approach? The world needs a cyber security reboot The digital world is already…
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…
Despite strong progress, demonstrating actual quantum advantage with early devices is still an elusive challenge. Expert opinion differs markedly on where and when initial value will come. Future large scale machines look great, but the overheads look daunting. With current error correction methods even a one million physical qubit machine may only be a modest…
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…
