The Delft team tested its leakage reduction unit in error-correction experiments on five and seven physical qubits, with no runs discarded. The authors wrote that further research is required at larger code distances and for other codes.
Most of the 53 peer-reviewed experiments ran as simulations or quantum-inspired programs on ordinary computers. Their authors tested 41 only on toy or reduced datasets. The reviewers found no explicit demonstration of a quantum advantage.
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.
The code Infleqtion used is guaranteed to flag any single error but not to correct one, apart from the loss of an atom. A full paper with methods, resource counts, and statistics is still to come.
Microsoft and Qolab researchers would call a logical qubit scalable only if a machine sustains it with repeated error correction and decodes errors in real time. DOE plans to pay for logical qubits under counting methods negotiated with each company.
IonQ researchers ran a real-time decoder on 12 cores of an Apple M4 Max and measured decoding delays that lengthened simulated run times by 0.02% to 11.53%. They generated all error-check data in a noise simulation, without quantum hardware.
Most first-day findings were bugs in submitted code, found with AI assistance. On day two, other researchers posted attacks on designs including Tins, Facto-DSA, MoFang, and Neulaser. None of the attacked designs has been standardized or deployed.
Apple expects its draft rules to require three cosignatures per certificate and seven-day validity, with operator applications opening by late summer 2027. For email, Apple will accept root certificates that pair ML-DSA with ECDSA or RSA.
NIST still supports buying and running FIPS 140-2 modules in existing systems. FedRAMP counted more than 500 modules in the FIPS 140-3 testing pipeline in July. At least seven validated FIPS 140-3 modules support post-quantum algorithms.
With TU Berlin's TrustBOM, a software provider can prove that listed packages are absent from its SBOM without sharing it. The researchers wrote that the guarantee covers only the SBOM as generated, which an SBOM tool can get wrong.
