What KetQat is

KetQat is a vendor-neutral registry for reproducible quantum error-correction and quantum-algorithm research: publishing benchmark results, comparing them under enforced scientific-comparability rules, and reproducing them. It is not a QPU marketplace, does not process payments, and does not store third-party cloud-provider credentials.

Accounts

You sign in with GitHub OAuth. You're responsible for what's published under your account, including via API tokens you create. Revoke a token immediately if you suspect it's compromised.

Publishing content

• Only submit content you have the right to share (see Licensing).
• Do not submit malicious, executable, or obfuscated content. KetQat validates result JSON against public schemas and never executes what you submit.
• Do not misrepresent demo, synthetic, or fabricated data as a real result. Demo records are explicitly badged; deliberately mislabeling submitted content is a violation.
• Do not claim a run is independently verified or reproduced unless it actually meets the verification-evidence criteria described on the run's page.

Visibility

Content you mark PRIVATE is visible only to you and administrators. Content you make public is licensed to others under the terms in Licensing and stays discoverable (including via search engines) even if you later change its visibility going forward -- copies made by others while it was public are not retroactively withdrawn.

Removal

We may remove content that violates these terms, applicable law, or a valid third-party rights claim, and may suspend accounts used for abuse (e.g. spam, credential stuffing against the API, attempts to publish executable payloads).

Review and attestation

An assessment can carry a badge saying a named person reviewed it. That badge requires an approval by somebody who did not request the review, recorded against the exact inputs they saw. If those inputs change afterwards, the badge stops applying rather than transferring to a revision the reviewer never read.

KetQat does not award that badge to itself, and a matching reproducibility hash is not it: a hash shows the bytes are unchanged, which is a different claim from somebody having checked the work. A review is one person's judgement recorded with their reason, not a guarantee by KetQat that an estimate is correct.

Estimates are estimates

Resource estimates describe what a computation would require under assumptions that are stated on every figure. They describe a machine nobody has built. KetQat does not predict when quantum hardware will outperform classical hardware for your problem, does not rank vendors, and does not draw an economic conclusion without a cost model you supply. What it will and will not tell you is set out in full on the limitations page.

No warranty

KetQat is provided as-is. Reproducibility hashes and verification evidence describe the process by which a result was checked, not a guarantee that the underlying science is correct -- always read the evidence, don't just trust a badge.
