# Rosetta Quantum

> Neutral verification of quantum algorithms. We measure, per problem class,
> whether quantum beats the best classical solver — and publish the raw evidence,
> including the negatives. Show, don't claim.

## Key pages
- [Evidence Ledger](https://rosettaquantum.com/ledger): verdicts by recipe and problem class — including published self-corrections (errata) that cite the original sealed file and never overwrite it
- [Problem classes](https://rosettaquantum.com/clases): the four-tier map that sorts catalogued algorithms by how real the advantage is today
- [Q-Ready](https://rosettaquantum.com/q-ready): post-quantum cryptographic exposure — for organizations that need to know how exposed they are by the cryptography they run today

Every response carries the sealed sha256 plus the raw URLs of two independent
public copies, so a claim can be checked rather than trusted. As of today the
archive reports **0 measured quantum wins** — that negative is the product.

## Q-Ready — post-quantum cryptographic exposure
For organizations that need to know how exposed they are by the cryptography they run today.
- **Cryptographic Exposure Map** — Your public surface discovered and measured: hostnames, cryptography per endpoint, providers detected. **US$0**
- **Migration Starter Kit** — The map, plus the critical path —which provider sets your deadline—, where you stand against your sector, and a 30/90/365-day plan derived from your own findings. **US$4,900**
