Q-Day & CRQC
Predicting when quantum computers will break cryptography: Q-Day timelines, the CRQC Readiness Benchmark, the CRQC Capability Framework, expert forecasts, and the regulatory deadlines that may matter more than the quantum timeline itself.

The CRQC Scorecard: How Close Is Each Quantum Modality to Breaking Your Encryption?
Yesterday, two papers landed that set social media on fire. Google Quantum AI published a landmark resource estimate showing that fewer than 500,000 superconducting qubits could break Bitcoin's elliptic curve cryptography in under nine minutes. Hours later, a team from…

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…

Q-Day: Predicting the Unpredictable
When will a quantum computer break RSA and ECC? Expert predictions range from "already happened in a classified lab" to "never" — and the honest truth is that nobody knows. Q-Day prediction is hard because it depends on simultaneous breakthroughs…

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…

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…

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…

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…

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,…

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…

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…

What It Will Actually Cost to Break RSA-2048: Energy, Hardware, People, and the Bill Nobody’s Talking About
Breaking one RSA-2048 key on a CRQC could cost $2–5 million when you add up energy, amortization, personnel, and facilities All three approaches share silicon's core advantages: compatibility with semiconductor industry infrastructure, small qubit footprint (~50 nm), and long coherence…

Q-Day Revisited – RSA-2048 Broken by 2030: Detailed Analysis
It’s time to mark a controversial date on the calendar: 2030 is the year RSA-2048 will be broken by a quantum computer. That’s my bold prediction, and I don’t make it lightly. In cybersecurity circles, the countdown to “Q-Day” or…

What Is Q-Day (Y2Q)?
Q-Day, sometimes called “Y2Q” or the “Quantum Apocalypse”, refers to the future moment when a quantum computer becomes powerful enough to break modern encryption algorithms. In other words, it’s the day a cryptographically relevant quantum computer (CRQC) can crack the…

The Enormous Energy Cost of Breaking RSA‑2048 with Quantum Computers
The energy requirements for breaking RSA-2048 with a quantum computer underscore how different the post-quantum threat is from conventional hacking. It’s not just about qubits and math; it’s about megawatts, cooling systems, and power grids. Today, that reality means only…

Breaking RSA Encryption: Quantum Hype Meets Reality (2022-2025)
To put it plainly, if you encrypted a message with an RSA-2048 public key today, no one on Earth knows how to factor it with currently available technology, even if they threw every quantum computer and supercomputer we have at…
