The 160 surveyed companies named the countries where they buy, sell, and manufacture, but not what they buy or in what volumes. China, whose companies were not invited, ranked sixth as a supplier location.
Xanadu researchers timed round trips of 16-byte messages between an AMD FPGA board and an AMD Threadripper CPU at a median 2.305 microseconds, first as a plain echo and then with a small lookup-table decoder. No quantum processor was attached.
G7 cybersecurity agencies addressed decision-makers rather than technical teams, set five priorities from raising awareness to writing PQC into cybersecurity requirements, and warned that organizations that delay could be excluded from contracting opportunities, including public procurement.
EY said the machine will handle sensitive work such as fraud detection and risk management. Its chief innovation officer said the immediate value is not in replacing classical computing and named post-quantum readiness as the near-term focus.
Shannon proved in 1949 that perfect secrecy for arbitrary data needs a random key at least as long as the data, used once. A product sold as perfectly secret with a shorter or reused key fails that test.
The senator who moved third reading said there was "no direct discussion" of quantum threats at the committee level. Under a separate Treasury Board notice, federal departments must move high-priority systems to post-quantum cryptography by the end of 2031.
AQTI said in a release that "research extrapolations suggest" the JVG method "will require less than 5,000 qubits" to break RSA. The preprint gives no such qubit count, and its authors called their runtime projections indicative scaling trends.
