This challenge of making quantum-enhanced AI (QAI) applications accessible for a wide variety of users lies at the heart of the PlanQK project. The project aims to develop an open platform and ecosystem for QAI to connect experts and developers as well as users, customers, service providers and consultants. The PlanQK platform will comprise QAI algorithms, applications and data pools. It will be the technical basis for the creation of a QAI community and facilitate the exchange of QAI knowledge and technology. In this way, the PlanQK platform will make quantum-enhanced AI available to industry and, in particular, SMEs and enable them to make use of these key technologies. The PlanQK project is one of 15 projects selected from more than 130 proposals initially submitted to the innovation contest "Artificial intelligence as a driver for economically relevant ecosystems" by the Federal Ministry of Economics and Energy (BMWi).
