Which US Federal Post-Quantum Deadline Binds You
Federal post-quantum policy now sets dates, not intentions. Five June 2026 documents assign different deadlines to different system classes. Here is how to find…
Why the World Can’t Agree on Hybrid PQC Deployment
Germany expects hybrid key exchange. Australia expects pure ML-KEM. The US sets a date for dropping the classical half. What to build when the…
A Field Guide to Misleading Quantum Marketing
Quantum vocabulary moves procurement budgets, and marketing has noticed. The two shapes a bad claim takes, four questions that tell them apart, and what…
Quantum-Safe, Quantum-Resistant, Post-Quantum: Which Word to Use
Three labels, one body of algorithms, and three different implied levels of confidence. What each word actually claims, and the three questions that make…
What Vendors Do When You Ask Hard Questions
A technical question deserves a technical answer. When a quantum security vendor substitutes something else, the substitution is your finding. A field guide to…
The Two Dates in NIST IR 8547 That Govern Your Migration Plan
NIST IR 8547 is usually reduced to 2035. It sets two dates, and the earlier one is already shaping procurement and risk acceptance decisions.
The Four Axes Where National PQC Requirements Diverge
Approved algorithm lists are the first of four axes on which national post-quantum requirements diverge. The other three are harder to abstract away.
Mosca’s Theorem: Working Out Your Own Quantum Deadline
Mosca's Theorem is one line of arithmetic, and most organisations get two of its three variables wrong. Here is how to estimate each one…
Post-Quantum Cryptography Standards: What Is Final and What Is Not
Three post-quantum standards are final, one is still pending, and roughly fifteen more algorithms are in competition. Here is where the boundary sits and…
NIST Security Strength Categories 1 to 5, Explained
NIST's five post-quantum security categories are floors, not bit counts. Here is what each one anchors to, how quantum cost models shape them, and…
