Quantum Computing for Cybersecurity Professionals
Part 1: What a Quantum Computer Is Not
The popular story of quantum computing gets the professionally important details backwards. Part 1 clears the category error, previews the cryptographic casualty list, and sets your real deadline, which arrives well before Q-Day.

Adiabatic Quantum Computing (AQC) and Impact on Cyber
Adiabatic Quantum Computing (AQC), and its variant Quantum Annealing, are another model for quantum computation. It's a specialized subset of quantum computing focused on solving optimization problems by finding the minimum (or maximum) of a given function over a set…

Routing Quantum Information: SWAP, iSWAP, and Moving Qubit States
Quantum computers face a unique challenge in moving quantum information between qubits. Unlike classical bits that can be shuttled freely along wires, qubits cannot be arbitrarily copied or moved due to the no-cloning theorem. To route a qubit’s state from…

Surface Code Quantum Error Correction
Quantum error correction (QEC) is indispensable for building large-scale fault-tolerant quantum computers. Even today’s best qubits suffer error rates that would quickly corrupt any long calculation if left uncorrected. The principle of QEC is to encode a single logical qubit…

What Model Inversion Attacks Actually Recover
Model inversion recovers class representatives more often than individuals, its dominant evaluation framework counts adversarial examples as successful reconstructions, and embedding inversion has become a separate privacy problem in enterprise retrieval systems.

Data Spoofing Is Four Attacks, and Your Model Answers None of Them
Channel authenticity, measurement integrity and model correctness are three separate properties, and no one of them supplies the other two. Sorting the four attacks that get filed under data spoofing, and the control that answers each.

How KuCoin Survived a Massive Hack of $285M Worth of Crypto Assets
When attacked, some crypto projects and exchanges buckle and fold under pressure; KuCoin set the standard in 2020 for how to react to crypto hacks, even on the largest scale. KuCoin is a Singapore-based crypto exchange that consistently ranks among…

The Open RAN Lexicon You Need
The telecoms and digital technologies sectors are notoriously jargonised. Eavesdrop on any conversation at an industry conference (remember those?) and you’d be treated to a parade of acronyms, initialisms and technical terms that would sound like ancient Greek to an…

Quantum Supremacy vs. Quantum Advantage
In the ever-accelerating world of quantum computing, two terms have emerged as the darlings of headlines and conference keynotes: quantum supremacy and quantum advantage. If you've followed the news, you might think they're interchangeable buzzwords celebrating the dawn of a…

CRQC Readiness Index Proposal
This proposal outlines a composite, vendor‑neutral “CRQC Readiness” indicator. It intentionally avoids one‑number vanity metrics (like only counting qubits) and instead triangulates from three ingredients that actually matter for breaking today’s crypto: usable (logical) qubits, error‑tolerant algorithm depth, and sustained…
