Quantum computers will efficiently solve problems that could not be solved in the past. Examples are calculations of properties of complex molecules for pharmaceutical industry or solutions of optimization problems for manufacturing processes in automotive industry or for calculations in the financial sector. Within the framework of the “GeQCoS“ collaboration project, Germany’s leading researchers in the area of superconducting quantum circuits are working on innovative concepts for designing better quantum processors. Researchers from Karlsruhe Institute of Technology (KIT) play an important role in the project.

The collaboration project “German Quantum Computer Based on Superconducting Qubits,” GeQCoS for short, is aimed at developing a prototype quantum processor consisting of a few superconducting qubits with fundamentally improved components. The main components of a quantum computer, the quantum bits or qubits, will be implemented by zero-resistance currents in superconducting circuits. These currents are relatively robust against external disturbances and can preserve quantum states during operation.

Novel Materials for Higher Quality of Qubits

The planned improvements will consist in an increase in connectivity, that is the number of connections among the qubits, as well as in the quality of qubits, that is the possibility to rapidly and efficiently produce the desired quantum states. “ Currently, this is a big challenge,” says Dr. Ioan Pop from KIT’s Institute for Quantum Materials and Technologies. “Use of novel materials for the production of qubits is expected to result in better reproducibility and higher quality of the qubits.”

Important Step towards the Development of Superconducting Quantum Circuits in Germany

To achieve improvement, researchers collaborate closely in the areas of alternative components, change of architecture, coupling mechanisms, and higher precision of calculations. “This is a very important step towards the development of superconducting quantum circuits in Germany. This technology is preferred and pursued by IT managers in the area of quantum computers,” Professor Alexey Ustinov, Head of the research group at KIT’s Physikalisches Institut, emphasizes. “Localization and diagnosis of errors is rather challenging work. We have to improve fabrication methods to prevent faults that sustainably influence the quality of the qubits.”

Today, quantum computers already are able to manage small specific problems and to exhibit basic functions, the experts say. In the long term, work is aimed at developing a so-called universal quantum computer that calculates important problems exponentially faster than a classical computer. An architecture suited for the calculation of practically relevant problems requires substantial improvement of both hardware and software.

Development Will Be Made Available to Innovative First Users

To reach this goal, scalable fabrication processes and optimized chip housings will be developed within the project. Eventually, the prototype quantum processor will be installed at the Walther Meißner Institute of the Bavarian Academy of Sciences. The technologies developed are not only expected to lead to new scientific findings. Close interconnection with companies will strengthen the quantum ecosystem in Germany and Europe. On both the hardware and software level, the quantum processor will be made available to innovative first users as early as possible.

Apart from KIT, the Friedrich–Alexander University Erlangen–Nürnberg [Friedrich-Alexander-Universität Erlangen-Nürnberg](DE) , Forschungszentrum Jülich Research Centre [Forschungszentrum Jülichs] (FZJ)(DE), Walther Meißner Institute of the Bavarian Academy of Sciences(DE), The Technical University of Munich [Technische Universität München](DE), Infineon, and the Fraunhofer Society [Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e. V.](DE) are involved in the project. The “GeQCoS“ project is funded by the Federal Ministry of Education and Research with EUR 14.5 million. Of these, more than 3 million euros go to KIT.

Mission Statement of KIT

Preamble

The Karlsruhe Institute of Technology-KIT [Karlsruher Institut für Technologie] (DE), briefly referred to as KIT, was established by the merger of the Forschungszentrum Karlsruhe GmbH and the Universität Karlsruhe ([TH] on October 01, 2009. KIT combines the tasks of a university of the state of Baden-Württemberg with those of a research center of the Helmholtz Association of German Research Centres [Helmholtz-Gemeinschaft Deutscher Forschungszentren] (DE) in the areas of research, teaching, and innovation.

The KIT merger represents the consistent continuation of a long-standing close cooperation of two research and education institutions rich in tradition. The University of Karlsruhe was founded in 1825 as a Polytechnical School and has developed to a modern location of research and education in natural sciences, engineering, economics, social sciences, and the humanities, which is organized in eleven departments. The Karlsruhe Research Center was founded in 1956 as the Nuclear Reactor Construction and Operation Company and has turned into a multidisciplinary large-scale research center of the Helmholtz Association, which conducts research under eleven scientific and engineering programs.

Being “The Research University in the Helmholtz Association”, KIT creates and imparts knowledge for the society and the environment. It is the objective to make significant contributions to the global challenges in the fields of energy, mobility, and information. For this, about 9,300 employees cooperate in a broad range of disciplines in natural sciences, engineering sciences, economics, and the humanities and social sciences. KIT prepares its 24,400 students for responsible tasks in society, industry, and science by offering research-based study programs. Innovation efforts at KIT build a bridge between important scientific findings and their application for the benefit of society, economic prosperity, and the preservation of our natural basis of life. KIT is one of the German universities of excellence.

In 2014/15, the KIT concentrated on an overarching strategy process to further develop its corporate strategy. This mission statement as the result of a participative process was the first element to be incorporated in the strategy process.

Mission Statement of KIT

KIT combines the traditions of a renowned technical university and a major large-scale research institution in a very unique way. In research and education, KIT assumes responsibility for contributing to the sustainable solution of the grand challenges that face the society, industry, and the environment. For this purpose, KIT uses its financial and human resources with maximum efficiency. The scientists of KIT communicate the contents and results of their work to society.

Engineering sciences, natural sciences, the humanities, and social sciences make up the scope of subjects covered by KIT. In high interdisciplinary interaction, scientists of these disciplines study topics extending from the fundamentals to application and from the development of new technologies to the reflection of the relationship between man and technology. For this to be accomplished in the best possible way, KIT’s research covers the complete range from fundamental research to close-to-industry, applied research and from small research partnerships to long-term large-scale research projects. Scientific sincerity and the striving for excellence are the basic principles of our activities.

Worldwide exchange of knowledge, large-scale international research projects, numerous global cooperative ventures, and cultural diversity characterize and enrich the life and work at KIT. Academic education at KIT is guided by the principle of research-oriented teaching.
