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…
Governing Quantum Sensors Before the Law Names Them
Quantum sensors produce measurements that most privacy statutes do not name and most sensor inventories do not describe. Here is how to classify them…
How Quantum Error Correction Actually Works
Bit flips, phase flips, stabilizers, thresholds and the arithmetic behind million-qubit roadmaps. A ground-up walkthrough of quantum error correction for engineers.
Harvest Now, Decrypt Later: Which Data Is Actually at Risk
HNDL is not a threat you defend against everywhere at once. It has a scope, and the scope is narrower than most briefings suggest.…
SBOM, CBOM, and the Rest of the Alphabet
Four bills of materials, four different questions. What each one answers, what belongs in a CBOM, and how to scope the work without stalling…
A Working Map of Quantum Sensing
Quantum sensing covers everything from the caesium clock in a telecom rack to a laboratory radar proposal. Here is a map organised by what…
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…
