You Can Now Build a Quantum Computer from Off-the-Shelf Components
In March 2026, a consortium in Denver assembled a working quantum computer from five different vendors' components in five months. A Dutch QPU, Dutch control electronics, an American cryostat, Australian calibration software, supply chain spanning three continents, integration in Colorado.…

France Answers the US CHIPS Act in 24 Hours, and NVIDIA Is Buying a Seat at Every Table
Macron added €1 billion to France's quantum strategy the day after the US committed $2 billion to quantum fabs. France's total quantum commitment now stands at €3.3 billion, and NVIDIA's investment in Alice & Bob landed the same afternoon.

Washington Isn’t Funding Quantum Research. It’s Building Quantum Factories.
Washington's $2 billion CHIPS Act quantum package isn't a research program. It's industrial policy — the U.S. is building quantum fabs, and that changes the calculus for everyone tracking the CRQC timeline.

“They’ll Just Rent One”: The Quantum Threat Model Nobody Bothered to Check
Every article about quantum threats includes the throwaway line: criminals won't need their own quantum computer, they'll just rent one. The actual evidence says otherwise.

PQC Governance: Who Should Lead Your Post-Quantum Migration, and How to Structure the Program
PQC migration is the most complex cryptographic transformation in enterprise history. Getting the governance model right determines whether it succeeds or stalls. Here's how to structure it.

Jiuzhang 4.0: China’s 1,024-Input Photonic Processor Claims 10⁵⁴ Speedup
Pan Jian-Wei's team published a rigorous Nature paper showing an order-of-magnitude leap in photonic quantum scale. The engineering is impressive. The "quantum supremacy" framing from state media is a different matter entirely.

NIST Narrows the Field: Nine Post-Quantum Signature Candidates Advance to the Third Round
NIST just narrowed 14 post-quantum signature candidates to nine. The survivors span four distinct mathematical families, from isogeny-based compact signatures to multivariate schemes under active cryptanalytic fire. Here's what each candidate is, why NIST kept it, and what this means…

India Finalizes Quantum-Safe Roadmap: CII Migration by 2029, Testing Labs by 2026
India's finalized quantum-safe roadmap adds Preferential Market Access mandates, a detailed four-level certification framework, and sector-specific technology guidance. The timelines hold — but the execution gap just got harder to ignore.

The 2027 Procurement Gate: Why CNSA 2.0 Compliance Starts Now
January 1, 2027 is when CNSA 2.0 stops being guidance and becomes a procurement gate. Combined with the FIPS 140-2 sunset in September and CMMC enforcement in November, it creates a five-month compliance squeeze that cannot be solved by urgency…

CNSA 2.0: The Complete Guide to NSA’s Post-Quantum Requirements
The definitive vendor-neutral reference to NSA's Commercial National Security Algorithm Suite 2.0 — the most operationally specific post-quantum cryptography mandate in the world. This guide breaks down every component of CNSA 2.0 in one place: the complete algorithm suite with…

CNSA 2.0 vs. the World: Navigating Diverging Global PQC Requirements
The world's major cryptographic authorities agree that post-quantum migration is necessary. They disagree on nearly everything else: which algorithms, which parameter levels, whether hybrid is mandatory, and whether NIST's standards are sufficient.

CNSA 2.0 for the Defense Industrial Base
CNSA 2.0 applies to National Security Systems. The requirements cascade to every prime contractor, sub-tier supplier, and commercial vendor selling into classified environments — arriving alongside CMMC 2.0 enforcement and a FIPS 140-3 validation bottleneck.

CNSA 2.0 Beyond NSS: Why Financial Services Is Adopting It Anyway
CNSA 2.0 technically applies only to National Security Systems. In practice, its algorithm choices are appearing in financial services procurement language, board-level risk assessments, and counterparty due diligence — creating a de facto standard for high-assurance cryptography far beyond its…

The SLH-DSA Exclusion: Why NSA Left Out NIST’s Conservative Fallback
NSA excluded NIST's hash-based signature algorithm from CNSA 2.0 and stated it does not plan to add future post-quantum standards. The decision reveals how NSA thinks about lattice security, operational simplicity, and the trade-offs that other national authorities resolve differently.
