What a Quantum Network Is Actually For
A quantum network does not carry your traffic. It produces a narrow set of outputs, and knowing exactly what those are is the difference…
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…
Getting Vendors to Answer the Right Questions
Most post-quantum vendor questionnaires ask about intent, and intent questions have one correct answer that every vendor knows. Four question shapes that don't.
Distributing Entanglement Across a Network: A Design-Level Guide
Loss, fidelity, and memory coherence set the shape of every quantum network. A working guide to direct transmission, entanglement swapping, and purification, with the…
Crypto-Agility in Practice: A Design Guide for Architects
Crypto-agility is measured in how long a substitution takes and how much of the system it touches. Here is what that means at the…
Quantum Teleportation, Precisely
Teleportation is a fully specified protocol with a fixed cost: one entangled pair, one joint measurement, two classical bits. Here is what it does…
Five Ways Post-Quantum Migration Programs Fail
Most post-quantum migration programs stall at the seams: certificate profiles, network paths, HSM limits, inventory gaps, and work nobody owns. Five failure modes, and…
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…
Planning the First Year of a Post-Quantum Program
Twelve months will not migrate an enterprise off RSA. It will produce an inventory, a working lab, a PKI that can issue post-quantum credentials,…
The Cryptography Inside a 5G Roaming Call
One roaming voice call crosses four trust domains and invokes symmetric, asymmetric and hash-based cryptography at every one. Here is the walkthrough, and what…
