How to Check Whether a TLS Connection Is Already Post-Quantum
Your browser, openssl s_client and curl can all show whether a connection negotiated X25519MLKEM768. Here's where to read the group name, what hybrid key…
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…
How to Choose a Quantum Control System
Control electronics decide whether a qubit chip ever computes. A selection sequence for engineers: latency budget, channel count, modality shortlist, and the supply constraint…
Preparing a Facility for a Quantum Computer
A quantum computer is a building problem before it is a physics problem. What the site survey measures, which four sign-offs the schedule depends…
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…
What Crypto Holders and Builders Should Do Now
No quantum computer can break blockchain signatures today. The published migration deadlines still bind. Here is what to do without waiting for anyone.
How to Estimate Post-Quantum Migration Effort
Two planners can size the same estate at 2,000 tasks and 120,000. Here is the unit to count, the ratio that catches a bad…
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…
Where Telecom Operators Should Start
The algorithms are settled. What stops most carriers is that nobody can yet read a cryptographic inventory and say which findings matter first.
Running a Sovereignty Stress Test That Can Fail
Most sovereignty tabletops end with the finding that the organization would cope, because nobody defined coping first. A design guide for an exercise that…
