About $200 million is new funding tied to the final stage of DARPA's Quantum Benchmarking Initiative. The rest is a proposed loan to PsiQuantum that the company said is conditional and not guaranteed.
IonQ and Duke researchers reported 1,032 entangled ion-memory pairs per second at 87.9% fidelity. In their preprint, they cited estimates that links between error-corrected modules need roughly 10 to 100 times that rate.
The four join Microsoft and PsiQuantum in Stage C, where government evaluators test whether a proposed utility-scale machine can be built as designed. Of the four, only Diraq disclosed its initial funding, $51 million for the next year.
Europol's cybercrime center named wallet signing keys as the main quantum exposure for cryptocurrencies. In a second report with a Madrid university, Europol rated government data at high risk from harvest-now, decrypt-later collection.
None of the 24 agencies GAO audited had fully carried out three preparatory steps for post-quantum migration. At six sampled agencies, none could document the algorithms listed for every sampled system.
Google and MIT researchers spread error-correcting codes across small chip modules, with 42 to 116 physical qubits in their main examples. They have not tested the design on hardware or estimated what a complete algorithm would cost on it.
The cabinet expects a quantum computer able to break public-key encryption between 2029 and 2035. Ministries are to fund the migration from existing budgets at first. The cabinet will adjust its ambitions if it cannot find the money.
NSA kept the five limitations it listed in 2020 and added an argument that QKD security established at certification can degrade. It dropped a line saying it did not expect to certify or approve QKD products.
No key for a real Classic McEliece parameter set has been publicly recovered. Even with a memory charge, one researcher's estimate is still below the claimed levels. BSI says hybrid deployments remain at least as secure as their classical half.
Allies approved NATO's first quantum technology roadmap on July 30. In its public summary, NATO dated activities through 2029, from sea trials of quantum navigation sensors to an Alliance quantum standards roadmap.
