Quantum computing news, stocks, companies and breakthroughs — the state of the quantum race in 2026 and beyond.
ETH Zurich built a fingernail-sized quantum chip that stores data as tiny mechanical vibrations, like a guitar string. More memory, longer coherence, smaller footprint, and it ran real algorithms.
Quantum computing normally requires a PhD and a language that looks like hieroglyphics. MIT and IBM just made a version where you can tell the machine what you want in English.
A plain-English roundup of the week’s major quantum computing news — the White House summit, Quantinuum’s IPO, IonQ’s $1.08B deal, Willow’s error-correction milestone and more.
IonQ is spending $1.08B on a UK rival, PsiQuantum is getting $100M in federal money, and Washington is taking equity stakes. The quantum supply chain is being bought up.
The biggest pure-play quantum IPO yet raised $1.68B — and closed flat on day one. A market watcher’s read on what Quantinuum’s debut says about quantum stocks.
Error correction crossed real thresholds, a supercomputer set a 50-qubit simulation record, and Washington started treating quantum like a strategic industry. The state of quantum in 2026.
Washington just turned quantum computing into industrial policy — and the stocks noticed. A market-watcher’s look at the $2B bet, the rally, and the valuations underneath.
IonQ trades near 100x sales. Rigetti above 800x. Insiders have sold ~$931M net. Here’s what the credible voices — Huang, Aaronson — say about whether the tech is close.
