The Hardening Decisions an Operator Has to Make
Eight hardening decisions that constrain a quantum computer's floor plan, network diagram, and hiring plan. All of them are cheaper to make before the…
Building a Crypto Inventory That Covers the Whole Estate
Cryptography hides in places no network scanner reaches. A domain-by-domain guide to finding it, and to what every inventory record has to say once…
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…
Following a Hybrid Job Through a Quantum-HPC Stack
A QPU next to a supercomputer is a demonstration. A QPU inside the job queue is a resource. Here is what sits between the…
Ethereum’s Five Quantum Vulnerabilities and Who Owns Each Fix
One network, three cryptographic primitives, five layers, five different sets of owners. Ethereum as a worked example in reading a cryptographic inventory.
Pick One Layer: Choosing the PQC Migration That Protects Most
Nested encryption composes in the defender's favor. One quantum-safe confidentiality layer protects the payload underneath it, which makes the first migration decision a choosing…
Why Signature Migration Needs the Longer Runway
A post-quantum plan is two migrations under one label. Sorting the signature work by who has to agree before you can change an algorithm…
The Four Seams of a Modular Quantum System
Open architecture only works where the interfaces do. Here are the four boundaries in a quantum system that an architect has to specify, test,…
Quantum-as-a-Service: How Access Actually Works
Shots, tasks, queues, transpilation and reserved time. A walk through the full access path from credentials to returned counts, with a worked shot budget.
Architecting for Quantum Cloud Workloads
A quantum processor reached over a network behaves unlike any accelerator you have integrated before. Four placement patterns, and the arithmetic that picks between…
