Quantum Computing

Hype-allergic note. Three things in a week: Infleqtion hit 30 logical qubits off 80 physical (neutral-atom, Sept 24), Quantinuum/MS posted logical error ~800x below physical, and the one I circled - IonQ ran real-time…

The strange thing about quantum risk: the harvest-now-decrypt-later attack means data stolen TODAY is already exposed to a computer that does not exist yet. Migration to post-quantum standards takes years, and most companies have…

Everyone's quoting logical-qubit counts - 48 on Quantinuum Helios, 96 on QuEra's neutral atoms, Willow at distance-7. Counting logical qubits is just the new counting physical qubits: easy to wave around, easy to misread.…

Hype-allergic quantum person, but 2026 changed shape for me. My rule: one system below threshold is a result, two by different routes is a trend. This year we got three. Willow (Google) showed logical…

Short answer: useful quantum advantage exists in a handful of narrow, mostly contrived problems. Practical, error-corrected machines that break RSA or design drugs are still years out — error correction is the real mountain,…

Everyone fixates on quantum breaking encryption. As a materials person, I think the first real wins are in simulation: modelling molecules and materials classical computers can't. Better batteries, catalysts, fertilisers. That's a quieter revolution…
