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…
Why Telecom PQC Migration Is Harder Than Enterprise Migration
Operators face two problems enterprises mostly don't: most of their cryptography is written by someone else, and every cryptographic relationship has a counterparty they…
The DiVincenzo Criteria and What They Screen Out
David DiVincenzo's seven requirements were written to stop a specific over-claim. A quarter-century later they still screen architectures, and they still refuse to rank…
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…
Sovereignty in Quantum Navigation Starts at Acceptance Testing
Quantum navigation and sensing are reaching field trials. The scarce national capability is not building the hardware, it is being able to verify it.…
Crypto-Agility When You Can’t Swap the Algorithm
Algorithm swaps almost never happen cleanly. A more useful definition of crypto-agility, and the four mitigation patterns architects can deploy before a full replacement…
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…
The Skills a Quantum-Ready Security Team Needs
Post-quantum migration stalls on staffing more often than on cryptography. Seven capability areas, who in your organization already covers them, and how to find…
