Governments committed $12.7 billion to quantum technology in 2025 and venture investors $4.9 billion, against a $1.9 billion market. Spin-offs combine both kinds of money. Companies that listed in 2026 have yet to show a shorter path to profit.
The Sydney company said it cut its February estimate by about an order of magnitude in qubit-time with its Pinnacle 1.2 update. It has not published the circuits, the decoder, or the hardware behind its decoding speed.
The US, China, and the EU now use export controls, investment rules, equity stakes, and their own standards to secure quantum technology. The EU has also drafted procurement preferences. Because quantum companies buy abroad, governments keep exemptions for partners.
NIST, the NSA, Britain's NCSC, the EU, Canada, and Australia all ask organizations to start post-quantum migration now. None claims a code-breaking quantum computer exists or gives it a known date. Their deadlines do not depend on either claim.
From a Finnish refrigerator at IBM to physicists trained in Britain, France, and Australia, U.S. quantum computers draw on other countries. Many domestic substitutes are years from scale, so Washington needs allied supply as well as factories.
The team restored error suppression in a stand-in test for logic gates by removing defective parts. The larger distance-5 code beat a distance-3 code only after the team discarded runs affected by leakage, and only in one basis.
Eighty-seven percent of the 1,001 IT and cybersecurity decision-makers polled for DigiCert reported post-quantum plans or work under way. Propeller Insights ran the survey in May, before a U.S. executive order set federal migration deadlines.
Regulators in five countries have acted or warned against products sold on the word "quantum." Generic claims about real technology get case-by-case scrutiny at most. Companies with real results face the same independent tests as everyone else.
Researchers reported in Nature Communications that eight physical qubits in a linear array kept their coherence. They demonstrated a two-qubit gate on one of four qubit pairs and reported no gate fidelities for the array.
Silicon spin qubits now come from 300 mm lines at imec, Intel, and STMicroelectronics. No maker has yet shown a fab supplying enriched silicon, qubits uniform enough to tune automatically at scale, or control electronics within a million-qubit power budget.
