In this joint project, Germany's leading scientists in the field of superconducting quantum circuits have teamed up to develop innovative concepts for the construction of an improved quantum processor. The technologies developed within GeQCoS will not only lead to new scientific knowledge, but also strengthen the quantum ecosystem in Germany and Europe through close links with companies. A specific goal is to make the quantum processor available to first-time users both on the hardware and on the software level as early as possible. With access to the processor developed in the project, companies in the quantum technology sector should be strengthened and new start-ups should be promoted. In addition, the project may serve as the nucleus of the current federal initiative to build a quantum computer 'made in Germany'.
