Q-FUD: The Quantum Panic Industry
Cybersecurity has always had a FUD problem. “FUD” (fear, uncertainty, and doubt) is the oldest trick in enterprise security marketing: paint a worst-case scenario, imply you’re already compromised, sprinkle in enough jargon to make the buyer feel outgunned, and then offer the “only” solution - conveniently available this quarter. Q‑FUD is that same playbook, just dressed in quantum vocabulary. Why is Q‑FUD uniquely toxic? Because…

Q-Day Isn’t an Outage – It’s a Confidence Crisis
Cybersecurity lore often paints Q-Day (the moment a quantum computer cracks RSA/ECC encryption) as an instant "Quantum Apocalypse" where every system gets hacked immediately. Planes falling from the sky, banks drained in seconds, an overnight digital Armageddon - if that nightmare doesn’t happen, some assume Q-Day wasn’t so bad after all. But this view misses a crucial point. The real catastrophe of Q-Day isn’t that…

Forget Q-Day Predictions – Regulators, Insurers, Investors, Clients Are Your New Quantum Clock
Whether you personally believe Q-Day will come in 5 years or 50, the world around you isn’t taking chances - and neither can you. As a CISO, you’re now being implicitly (and sometimes explicitly) told by every corner of your ecosystem that quantum preparedness is mandatory. Regulators demand it via hard deadlines. Key clients and partners demand it in contracts and RFPs. Insurers will soon…

How You, Too, Can Predict Q-Day (Without the Hype)
For three decades, Q-Day has been “just a few years away.” I want to show you how to make your own informed prediction on when Q-Day will arrive. Counting physical qubits by itself is misleading. To break RSA you need error‑corrected logical qubits, long and reliable operation depth, and enough throughput to finish within an attack‑relevant time window.

CRQC Readiness Benchmark vs. Quantum Threat Tracker (QTT)
I will try and compare my proposed CRQC Readiness Benchmark with QTT, highlighting fundamental differences in methodology, assumptions, and philosophy, all in an effort to clarify how each approach informs our understanding of the looming “Q-Day.” The goal is to articulate why my benchmark and QTT produce different outlooks (2030s vs. 2050s for RSA-2048), and how both can be used together to guide post-quantum readiness.

The Trouble with Quantum Computing and Q-Day Predictions
The trouble with quantum computing predictions so far has been that too many have been more speculation than science, more influenced by bias than by balanced analysis. We have the tools and knowledge to do better. By embracing a data-driven, scenario-based approach, we can turn timeline forecasting from a source of confusion into a valuable planning aid.

Quantum Threat Tracker (QTT) Review Praising the Tool Questioning the Demo
The Quantum Threat Tracker (QTT) is a newly released open-source tool by Cambridge Consultants and the University of Edinburgh that aims to forecast when quantum computers will break today’s encryption. It combines quantum resource estimation (using optimized variants of Shor’s algorithm) with hardware development roadmaps to predict when cryptographic protocols will be broken. In other words, QTT estimates how many qubits and runtime are needed…

CRQC Readiness Benchmark – Benchmarking Quantum Computers on the Path to Breaking Cryptography
Benchmarking quantum capabilities for cryptography is both critical and challenging. We can’t rely on any single metric like qubit count to tell us how near we are to breaking RSA-2048. A combination of logical qubit count, error-corrected circuit depth, and operational speed must reach certain thresholds in unison. Existing benchmarks – Quantum Volume, Algorithmic Qubits, etc. – each address parts of this, but a CRQC-specific…
