What Quantum Sensors Are Used For
Four measured quantities cover almost every quantum sensor on the market. Sorting by quantity instead of by industry tells you the baseline, the failure…
How to Perform a Cryptographic Inventory: A Discovery Method Field Guide
Nine discovery methods, what each one actually finds, where each one goes blind, and how to layer them so one tool's gap is another…
Why You Can’t Just Drop In Post-Quantum Cryptography
The algorithms are standardized. The plumbing around them was sized for 32-byte keys. Here is where post-quantum objects break real infrastructure, and what to…
Cryptographic Competence: What Your Engineers Need to Know
The post-quantum migration is an engineering problem, not a mathematics problem. Here is what competence looks like across the four domains that carry the…
Post-Quantum Cryptography in OT: Sort the Fleet Before You Plan the Migration
Most PQC migration advice assumes you can change the code that checks a signature. In OT you often can't. Sorting assets by verifier agility…
What Larger Keys Do to Your Network
A hybrid TLS handshake carries about 1,216 bytes where a classical one carried 32. We count the whole first flight and follow it across…
How Quantum Error Correction Actually Works
Bit flips, phase flips, stabilizers, thresholds and the arithmetic behind million-qubit roadmaps. A ground-up walkthrough of quantum error correction for engineers.
Where Trust Sits in a Quantum Network
Quantum key distribution moves the trust boundary rather than removing it. A working guide to trusted nodes, device-level attacks, and the questions to ask…
Cryptographic Inventory: What Works, What Fails, and Why
A practical guide to running a cryptographic inventory that survives contact with a real environment: what interviews are good for, what tooling catches, and…
Entanglement-Based QKD: How E91 and BBM92 Actually Work
E91 and BBM92 both distribute entangled photon pairs, but they verify security in completely different ways. That difference decides what you have to trust.
