Quantum Computing – complementing the quantum computing FPAs with the development of a technology agnostic software stack (RIA)

Quantum APIs and cloud access form the transition layer between users and quantum machines in the quantum computation stack. This layer includes general-purpose quantum software development kits that are used to implement quantum algorithms for both gate-based systems, simulators and quantum annealers. This call seeks proposals that address the creation of a cohesive software stack that is agnostic to quantum hardware, facilitating the development, testing, and deployment of quantum applications across various platforms.

Proposals are encouraged to build on, or seek collaboration with, existing projects, and develop synergies and ensure complementarities with other relevant European, national, or regional initiatives and funding programmes. In particular, links are encouraged with the following, as well as with the EuroHPC Joint Undertaking:

• HORIZON-CL4-2021-DIGITAL-EMERGING-02-17: Framework Partnership Agreement for developing large-scale quantum simulation platform technologies (FPA)
• HORIZON-CL4-2021-DIGITAL-EMERGING-02-15: Framework Partnership Agreement for developing the first large-scale quantum computers (FPA)
• HORIZON-CL4-2023-DIGITAL-EMERGING-01-43: Framework Partnership Agreement for developing large-scale quantum Computing platform technologies (FPA)
• HORIZON-CL4-QUANTUM-02-SGA - Developing large-scale quantum simulation platform technologies (SGA)
• HORIZON-CL4-QUANTUM-01-SGA - Developing the first large-scale quantum computers (SGA)

In addition, proposals are expected to develop synergies with relevant projects funded under the Digital Europe Programme (DEP).

Proposals should also contribute to spreading excellence across Europe; for example, through the involvement of EU Widening Countries.

In this topic the integration of the gender dimension (sex and/or gender analysis) in research and innovation content is not a mandatory requirement; however, should proposers consider it to be of relevance for their proposal, they are strongly encouraged to integrate it.
