Six days ago, IBM agreed to buy a quantum-computing lab that builds a kind of qubit IBM does not. This week, the lab showed the world why. HRL Laboratories published a result in Nature on Wednesday: a silicon quantum processor that, in effect, runs its…

ZuriQ, a Swiss quantum computing company spun out of ETH Zürich, has raised $25.5 million in a seed round to scale the trapped-ion processors it is building on a new two-dimensional architecture. The money builds on the $4.2 million pre-seed round the …

France’s Pasqal is heading to Nasdaq at a $2bn valuation, roughly 100 times its revenue. Its own filings spell out two things. Quantum computing might never pay off. And Paris can veto who owns the company. Pasqal, the French quantum-computing firm, is…

PsiQuantum has broken ground on a facility in Moreton Bay, Queensland, where it plans to build and deploy what it calls the world’s first utility-scale, fault-tolerant quantum computer. The site will eventually hold tens of thousands of photonic quantu…

Most quantum-computing startups ask the world to build them an entirely new industry: exotic materials, bespoke fabrication, supply chains that do not yet exist. Quobly is making a quieter bet. The Grenoble company thinks the path to a useful quantum m…

IBM stock surged 10% on Monday after Barclays initiated coverage with an overweight rating and a $350 price target, roughly 11% above the opening price. The jump extends a run that has seen IBM gain nearly 30% in May alone, its best monthly performance…
