What a CBOM Is and What It Is For
A CBOM is a machine-readable list of the cryptography inside a system. Here is what it records, the questions it answers, and the four…
The Machine That Breaks Encryption Won’t Be One Chip
Threat assessments still track one qubit count on one processor. The machine that matters for cryptography looks more like a data center than a…
Why You Can’t Just Drop In Post-Quantum Cryptography
The algorithms are standardised. The plumbing around them was sized for 32-byte keys. Here is where post-quantum objects break real infrastructure, and what to…
Quantum Repeaters: What an Architect Needs to Know Before the Sales Call
A quantum repeater is not an amplifier. It is a machine that manufactures entanglement in segments and stitches them together. Here is how it…
Entanglement-as-a-Service: What Is Actually Being Sold
Entanglement can be delivered on demand, but it cannot be copied, amplified, or stored for long. Here is what an EaaS offer contains and…
Turning NIST SP 1800-38 Into a Governance Work Plan
NIST's practice guide on post-quantum migration is a lab record, not a mandate. A GRC reading of its three volumes, and the four artifacts…
Quantum Networks in Orbit: Who Controls Which Layer
Satellite QKD turns a physics result into infrastructure. For architects, the useful question isn't who owns the satellite. It's which layer of the stack…
Quantum Memory and Why Networks Need It
Quantum networks fail past a few hundred kilometres without a component that has no classical equivalent: a device that holds a qubit without reading…
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.
Harvest Now, Decrypt Later: Which Data Is Actually at Risk
HNDL is not a threat you defend against everywhere at once. It has a scope, and the scope is narrower than most briefings suggest.…
