Official quantum software from KetQat, run on your own computer.
KetQat selects, prepares, verifies and maintains quantum software in three categories: Quantum Algorithms, Quantum Error Correction and Quantum Information. Find a product in the catalog, copy its command, and run it locally with the KetQat SDK. Free products need no account, no payment and no telemetry.
pip install "ketqat[algorithms] @ git+https://github.com/ketqat/ketqat-sdk@c9c7ca466eed078d8d740d4333897ca5858df217#subdirectory=python"
ketqat catalog search
ketqat catalog run grover-search@1.0.0 --param n_qubits=5 --param marked=3 --seed 7The package is not on PyPI yet. Until the first release, install from the pinned public commit shown above. Every product records its version, parameters, seed, environment and a result hash in a local run record, so you can reproduce a run.
Each product states who invented the method, which open-source code it builds on and under what license, and what KetQat did. "Officially provided by KetQat" does not mean KetQat invented it. Products list their assumptions, scope and limitations, and say how they were validated.
Pro adds further KetQat implementations and workflows for local use under a signed, time-limited entitlement. It is not on sale yet; any price shown is a proposal.
ketqat-sdk: the catalog definitions, the Python SDK and CLI that run products locally, public contracts and reproducibility hashing. Apache-2.0.ketqat-benchmarks: heavier benchmark and differential-validation instruments kept out of the SDK.ketqat-web(private): the ketqat.com catalog, profiles, reviews and Pro distribution.ketqat-planning(private): vision, roadmap, ADRs and cross-repository planning.
Anyone can improve KetQat products through pull requests, issues, documentation and scientific validation in the public repositories. KetQat publishes and maintains the official products, and adopted contributions keep their contributor and original-author credit.
Open bugs and feature requests in the repository that owns the implementation. Security reports follow the security policy of the affected repository. Do not post secrets, credentials, private datasets or undisclosed vulnerabilities in public issues.
