About KetQat

KetQat publishes an official catalog of quantum software in three categories: Quantum Algorithms, Quantum Error Correction and Quantum Information. KetQat selects, prepares, verifies and maintains each product. You find a product here and run it on your own computer with the open-source Python SDK.

Every product page states who invented the method, which open-source software it builds on and under what license, and what KetQat did. “Officially provided by KetQat” never means “invented by KetQat”.

Free products, the SDK and its documentation are open source (ketqat-sdk on GitHub). Pro adds further KetQat implementations and workflows, which also run locally.

KetQat was founded in 2026, as stated on its LinkedIn company page.
