SUQCES - Manufacturing scalable and industry-compatible quantum computing approaches.

In addition to the development of software and algorithms, the development of proprietary technologies for the production of scalable and industry-compatible quantum computing approaches is crucial for future Saxon, German and European technological sovereignty. The goal in the SUQCES project is to record and evaluate the know-how and technical competencies in this field that exist primarily regionally in Saxony in order to assess Saxony's opportunities and potential for the field of quantum computing. In addition, the strategic initiative of the German government for the development of a quantum computer Made in Germany is to be supported significantly.

One focus of the project is on the fabrication of qubits. Concrete approaches, which have both high potential for industry-oriented scalability and existing competences in Saxony and Germany, are Si/SiGe, Si-MOSFET as well as superconducting qubit technologies. But also other promising candidates such as qubits based on color centers, ion traps, photonic or topological approaches shall be considered neutrally and open-ended. Besides the actual qubits, an effective and integrable control (readout and manipulation) and communication between the qubits has to be realized, both on design and technology level. Equally important is the development of new and optimized materials, processes and integration concepts of cryoelectronics as well as packaging and interconnection technology. In addition, accompanying modeling and the corresponding characterization and measurement technology play a major role. All mentioned aspects will be considered and addressed in the project.

With such a holistic approach, the foundation for a comprehensive platform for the evaluation and integration of qubit concepts can be laid. Ideally, such a platform will build on existing technologies in microelectronics and enable the qubit count required for quantum computing with error correction. This will be necessary to establish a concrete, realistic and sound plan for the ambitious goal of a German universal quantum computer.

The study achieved in SUQCES should thus contribute significantly to assessing the opportunities and potentials for quantum computing in Saxony as comprehensively as possible and to evaluating them especially with regard to microelectronics.
