Claudia Buch, who chairs the ECB's Supervisory Board, told bank chief executives that adopting post-quantum cryptography "must start now." She attached no deadline and said the ECB would address quantum risk in a separate letter.
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.
Coordinated by LuxQuanta, the six-member QUARTERNEXT consortium plans 48 months of work on continuous-variable QKD equipment and intends to provide its hardware and software for testing at Nostradamus, the EU's QKD evaluation effort.
Azure CTO Mark Russinovich cited quantum research progress and U.S. and French government actions. In its 2025 roadmap, Microsoft had aimed to complete the transition by 2033 and to enable early adoption by 2029.
The Quantum Flagship had announced the academy's launch in May. The academy aims to train at least 600 people in master's- and doctoral-level programs by the project's end and to deliver training to 5,000 learners.
SRI International is setting up the center, with cryostats and lasers among its first focus areas. SRI said an early goal is to make quantum-enabling components more manufacturable within three years.
Henry Legg of the University of St Andrews disputed a 2025 Microsoft paper, citing coding errors and omitted data. Microsoft researchers called one error a minor bug. Microsoft's Chetan Nayak said the company stands by its results.
The Forum narrowed more than 1,200 AI-generated nominations to 10. The report's authors wrote that hardware still limits quantum simulation and recommended mandated timelines for post-quantum migration.
National security systems must support the NSA's CNSA 2.0 algorithms. The department ruled out quantum key distribution for quantum resistance and will count solutions as fully post-quantum only with post-quantum authentication.
Under Trump's executive order, OMB must require agencies to move high value assets and high impact systems to post-quantum key establishment by 2030. Contractors would face that date through a procurement rule due in proposed form by December 19.
