The quantum headline in 2026 isn't the logical-qubit count - it's that a second route crossed threshold

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.…

Three different machines crossed break-even this year. Quantum is finally a trend, not a press release.

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…

Is quantum computing here? A researcher's reality check

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,…

What quantum will actually change first (hint: not Bitcoin)

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…
