# Q-CTRL

> Q-CTRL builds infrastructure software to power the quantum future — AI-driven quantum control, error suppression, and performance-management tools spanning quantum computing and quantum sensing. Products are consumed through official Python clients that call the Q-CTRL cloud (a hosted GraphQL API); there is no public REST/OpenAPI surface.
