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…
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…
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…
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…
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…
What Larger Keys Do to Your Network
A hybrid TLS handshake carries about 1,216 bytes where a classical one carried 32. We count the whole first flight and follow it across…
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…
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…
