Programme

Quantum computing plays a key role in Germany’s goal of establishing itself as a leading hub for future digital technologies. Consequently, in the High-Tech Agenda Germany the Federal Government has set itself the target of making two quantum computers of the highest European standard available by 2030.

Challenges and need for action

However, current efforts towards the commercial use of quantum computers have so far often been limited to exploring individual use cases or implementing exemplary proof-of-concept solutions. At the same time, the programming and handling of quantum computers currently still require considerable effort, multidisciplinary expertise and hardware- and application-specific customisation. This makes it considerably more difficult for many companies to access quantum computing and put it to practical use.

To tap into the significant value-creation potential of quantum computing, potential users therefore need low-threshold access to this technology. The development of suitable software abstraction layers and components, as well as their efficient interaction, plays a key role.

QC Next Technology Programme: Objective and Approach

As a flagship initiative of the High-Tech Agenda Germany, the Federal Ministry of Research, Technology and Space (BMFTR) is funding the development of a comprehensive modular software stack through the QC Next technology programme. At the heart of the programme is the design of an overarching, open reference architecture with uniform, standardised interfaces, which will be validated using concrete applications from industry and supplemented by process models and further software components.

On this basis, quantum computing solutions are to be developed more systematically and integrated more easily into existing industrial processes. At the same time, providers of quantum computing hardware and software are offered new opportunities for innovative business models as well as simplified access to potential customers. The technology programme thus contributes to the establishment and strengthening of a robust quantum computing ecosystem in Germany and Europe.

Structure: Flagship and satellite projects

The development of a widely accepted, modular software stack requires the coordinated collaboration of numerous partners. The QC Next technology programme specifically addresses this ecosystem concept by combining a central flagship project with complementary satellite projects.

The flagship project will develop the reference architecture as the structural framework for the software stack, as well as initial implementations of all necessary components. The satellite projects, on the other hand, will identify the industrial requirements of various use cases, validating the reference architecture and supplementing the software stack with specific software components.

Together, this creates a modular system with interoperable software components for a wide range of use cases. Supported by blueprints and suitable process models, this system is intended to significantly facilitate the industrial deployment of quantum computers. At the same time, it forms the core of an open ecosystem that plays a central role in the acceptance and widespread adoption of the software stack.

Funding framework

Funding is targeted towards research and development projects from consortia between academia and industry at Technology Readiness Levels 4 to 7. Subject to available budgetary funds, up to 38 million euros are available for the technology programme.
