Near-perfect qubit is a vague and ambiguous but useful term in quantum computing for describing qubit fidelity. It is somewhere between a noisy qubit and a perfect logical qubit or fault-tolerant qubit, no longer so noisy, but still not quite as perfect as with full quantum error correction (QEC). In…

I have mixed feelings about IBM’s announcement of its 127-qubit Eagle quantum computer. Yes, it’s a significant engineering achievement, but it doesn’t actually offer any significant benefit to typical quantum algorithm designers or quantum application developers since that engineering is under the hood where they won’t see it, even for…

Here are my top wishes for developments in quantum computing for Christmas in 2021. Okay, that’s too tall an order with too little time left, so this informal paper lists the quantum computing developments I really want to see in the coming year, 2022. It’s a fun list, but it’s…

Premature commercialization of quantum computing will be counterproductive and lead to unnecessary disenchantment with the long-term potential for quantum computing. Despite the dramatic progress of quantum computing in recent years, many significant obstacles remain before commercialization can even begin. …

Quantum computing is a very long way from being ready for commercialization. This informal paper lays out a proposed model of the main areas, main stages, major milestones, and toughest issues, and a process through which quantum computing must progress before commercialization can begin in earnest, when all significant technical…

Despite the great progress in development of quantum computing in recent years, much research is still very much needed on all fronts of quantum computing, and quantum information science overall, before the field is truly ready for commercialization and deployment of production-scale production-quality practical real-world applications to address production-scale real-world…

NISQ quantum computers are by definition noisy and intermediate scale. That begs the question of what to call a quantum computer which is not noisy or not intermediate scale. This informal paper proposes a collection of alternative terms which reflect the future arrival of quantum error correction (QEC) for fault-tolerant…

Achieving quantum advantage over classical computing is the holy grail goal of quantum computing, but that’s a very steep hill to climb. There is no generally accepted qualitative or numeric metric for how much of a performance advantage of a quantum solution over a classical solution constitutes true quantum advantage…
