13 partners are advancing the European quantum software infrastructure to enable industrial adoption

Kickoff for EuroQSS: The European research and innovation project aims to develop an open, interoperable quantum software stack, balancing hardware specifics with abstraction. This infrastructure is intended to support hybrid workflows across different quantum computers and classical high-performance computing systems.

Thirteen European partners from industry and academia are participating in EuroQSS; the project will run from October 2026 through the end of September 2029.

The EU project EuroQSS (Universal European Quantum Software Stack) intends to provide a unified software stack in Europe that significantly simplifies access to quantum resources while enabling seamless collaboration between classical and quantum-based computing methods.

This common software layer will enable companies and research institutions to create applications that utilize the full potential of each quantum hardware modality without adaptation. EuroQSS thus follows an approach similar to that of established software platforms in classical IT: the complexity of the underlying hardware is abstracted, while users benefit from a unified development and runtime environment. In addition, the project prepares the software stack for future fault-tolerant quantum computers and contributes to European standardization activities for quantum software.

CSH will bring in know-how in data security, necessary for secure and successful design and implementation of the QSS (WP3 Blueprint and validation of the EuroQSS). Furthermore, CSH will be involved also in WP6 „Evaluation, benchmarking & recommendation system“ with its expertise on benchmarking quantum computing. The institute will bring further know-how from practical aspects of  benchmarking, standardization and certification of quantum devices.
