Fidelity Digital Assets Maps Bitcoin Quantum Resistance Options

Fidelity Digital Assets published a September 1, 2026 research note on Bitcoin quantum resistance, written by Daniel Gray. The note says a future cryptographically relevant quantum computer could threaten ECDSA and Schnorr private-key control once public keys appear on chain. Readers can review the SHRINCS design, signature-size trade-offs, and the soft-fork path Fidelity outlines for holders and custodians.

Langworthy Introduces American Quantum Competitiveness Act

U.S. Representative Nick Langworthy introduced the American Quantum Competitiveness Act on August 31, 2026, making the Secretary of Commerce principal advisor to the President on commercial quantum technology and trusted supply chains. A public competitiveness strategy would be due within two years of enactment and every three years after. Full statutory duties, corridor geography, and industry quotations are in the article.

ThinkQuantum and University of Padua Demonstrate 18 km Free-Space QKD

Researchers at the University of Padua and ThinkQuantum have demonstrated intermodal quantum key distribution over an 18 km free-space link in northeastern Italy. Adaptive optics at a 410 mm urban telescope coupled the telecom-wavelength signal into single-mode fiber and produced secret keys at about 200 bit/s with room-temperature detectors. Link parameters, detector comparison, and network-design implications are covered here.

Researchers Map Six-Stage STRIDE Threats Across Quantum-as-a-Service Pipeline

Researchers from the University of Jyväskylä have released a six-stage STRIDE threat model that maps attack surfaces across the full Quantum-as-a-Service pipeline used by IBM Quantum, Amazon Braket, and IonQ. The matrix organizes published quantum attacks, classical inheritances, and under-studied gaps, while identifying three cross-stage chains that elevate overall risk. Full technical details and the threat matrix appear in the arXiv preprint accepted as a QCE26 poster.

HAWK Lattice Signature Scheme Withdrawn from NIST Round 3 After AI-Assisted Key-Recovery Attack

An improved key-recovery attack discovered primarily by Anthropic’s Claude Mythos Preview led the HAWK team to withdraw the lattice-based signature scheme from NIST’s third-round additional signatures process within roughly 17 hours of public disclosure. The attack applies known lattice techniques more thoroughly than prior human review and does not affect finalized standards ML-KEM or ML-DSA. The rapid timeline underscores why measured crypto-agility forms a practical component of post-quantum migration planning.
