Q-Day · Abyssal Group

Quantum risk, made understandable.

A native countdown and radar for the post-quantum transition. Follow public signals, read the sources, and prepare without fake precision or panic.

Explore the approach ↓

Estimate, not prophecy

Scenario ranges make uncertainty visible instead of pretending there is one exact Q-Day date.

Radar with sources

Track quantum companies, standards and public signals with a source-backed article behind every profile.

Prepare early

Understand harvest-now-decrypt-later and the practical path towards post-quantum cryptography.

A calmer way to prepare.

Q-Day separates what is known, what is estimated and what is still uncertain. It is designed for people who need to understand the transition before they need to act.
