Pick One Layer: How to Choose the Post-Quantum Migration That Protects the Most
Recent research proves one post-quantum layer can protect all payload confidentiality. But which layer should you migrate first? Six enterprise architecture scenarios analyzed.

Quantum Snake Oil: A Field Guide to Misleading Quantum Technology Marketing
Sixteen terms. Two tracks. One field guide. The quantum technology market has the exact conditions that produce fraud in every emerging sector: high buzz, big money, low buyer literacy, and complex underlying science that most decision-makers cannot independently evaluate. This…

The Anatomy of Quantum Denial: What Bitcoin’s Response to the Quantum Threat Teaches Every CISO
At Bitcoin 2026, the same main stage hosted engineers building quantum-resistant upgrades and a trio claiming quantum computers can never work because Bitcoin proves time is discrete. The dysfunction that produced this scene plays out in every enterprise boardroom facing…

Quantum Security: A Complete Guide for Security Leaders
Sixteen concepts. One imperative. The quantum threat to cryptography is no longer a future concern — the deadlines for action are already set, and most organizations haven't started. This guide maps the complete quantum security landscape for CISOs and security…

Crypto-Agility Is an Architecture Problem, Not a Library Swap
Every PQC migration guide tells you to "be crypto-agile." After leading migrations at Fortune Global 500 scale, I can tell you where that advice fails: HSMs that can't upgrade, protocols with hard-coded algorithms, and embedded devices that will outlive the…

The Signature Supply Chain: How Deep Does Digital Trust Go?
From TPM attestation keys to container image signatures, modern systems depend on dozens of signature layers most security teams have never fully mapped. This deep dive exposes the full anatomy of the trust infrastructure a quantum computer would compromise.

PQC Standards Fragmentation: What Multinationals Must Plan For Now
Your New York office runs ML-KEM per NIST. Your Frankfurt office needs ANSSI-recommended hybrids. Your Shanghai office will require Chinese ICCS algorithms. Your Seoul subsidiary uses KpqC. You need one migration plan. This article maps how to build it.

The Decoder Bottleneck: The CRQC Challenge Nobody Is Talking About
Qubit count gets the headlines. Error rates get the analysis. But the classical decoder that must process millions of error signals per second in real time gets almost no attention outside the QEC research community. It may be the capability…

Grover’s Algorithm vs AES – Why “Ignore It” Is Almost Right
The consensus says Grover will never break AES-128. The math checks out on today's assumptions. But those assumptions are built on surface codes and superconducting hardware, and the ground is already shifting. Scan the quantum computing coverage of Bitcoin and…

PQC Signature Migration Before Encryption: Why Trust Infrastructure Comes First
Most PQC migration guides tell you to protect data first. But recent research confirms that signature algorithms fall faster, and the blast radius of a compromised signing key dwarfs that of a decrypted session. Here's why I'm telling CISOs to…

The CRQC Scorecard: How Close Is Each Quantum Modality to Breaking Your Encryption?
Yesterday, two papers landed that set social media on fire. Google Quantum AI published a landmark resource estimate showing that fewer than 500,000 superconducting qubits could break Bitcoin's elliptic curve cryptography in under nine minutes. Hours later, a team from…

Post-Quantum Cryptography Migration Frameworks: A Definitive Survey Through March 2026
A comprehensive survey of every post-quantum cryptography migration framework published through March 2026 — from ETSI TR 103 619 and the Dutch PQC Migration Handbook to the PQCC Roadmap and NIST SP 1800-38. Each framework is assessed against the capabilities…

No One Has Secretly Broken RSA-2048 or RSA-4096 — Here’s the Science
If someone tells you RSA-2048 or even RSA-4096 has been secretly cracked, they are either lying to you or have been lied to. There is no third option that is consistent with physics, engineering, the observable behavior of governments and…

Bitcoin’s Quantum Timeline Is Not RSA’s Quantum Timeline
Most quantum-risk-to-Bitcoin analyses rehash RSA-2048 timelines. They're missing the point. Bitcoin doesn't use RSA. It uses 256-bit ECC - and Shor's algorithm will break that first. Scan the quantum computing coverage of Bitcoin and you will find a remarkable pattern.…

Q-FUD: The Quantum Panic Industry
Cybersecurity has always had a FUD problem. “FUD” (fear, uncertainty, and doubt) is the oldest trick in enterprise security marketing: paint a worst-case scenario, imply you’re already compromised, sprinkle in enough jargon to make the buyer feel outgunned, and then…
