The story of the week: Treasury Proposes Wider Controls on Quantum Investment
Treasury has proposed expanding outbound investment restrictions to cover software and algorithms for quantum technologies, alongside controls on quantum hardware and related systems. The proposal is open for public comment through December 7, 2026, while existing rules remain in effect.
