Project fact sheet


The independent research and development of quantum computers is a central building block of sustainable digital sovereignty for Germany. The platform of superconducting integrated circuits for quantum computing is a world leader and has a clear scientific and technological agenda. The focus on high-precision, low-fault devices and stringent system integration as well as integration into classical high-performance computing allows more and more to tap this potential for industrial and academic use.

Goals and procedure

In this project, a quantum computer demonstrator with processor generations of different performance profiles (size, precision, application reference) based on superconducting circuits will be created. The core element is the combination of a qubit double strand with resonators. The circuits achieve their high quality through precise fabrication and analytics coupled with detailed modeling. System integration is guided by a tightly tuned software and firmware stack. A supply chain of supporting technologies is being established in preparation for further scaling steps.

Innovation and prospects

At the end of the project, several quantum demonstrators will be externally accessible via the Jülich Supercomputing Centre. The demonstrators will be able to be used efficiently through tight integration into the infrastructure, with already demonstrated applications e.g. in the design of new materials and optimization of the properties of existing materials. With the supply chain established in the project, the next scaling stage to increase performance is already addressed. This supply chain can set the first standards for quantum computing components.
