Quantum computing is a new technology that recently raises a lot of interest in industry. We will sketch the essentials of this technology and its properties that make it so interesting for applications. But quantum computing is radically different from classical computing such that new approaches for building software that encompass quantum computing is needed. We will sketch such differences and suggest a first attempt of a lifecycle of quantum software that evolved from projects the speakers are engaged with. Also, some building blocks of a corresponding development environment and execution infrastructure will be discussed that have been developed in projects. Selective areas that demand significant research will be pointed to.

About Frank Leymann

Frank Leymann, our first Kurt Gödel Visiting Professor, studied Mathematics, Physics, and Astronomy at the University of Bochum, Germany. After receiving his master degree in 1982, he pursued his PhD in Mathematics in 1984. Afterwards, he joined IBM Research and Development and worked for two decades for the IBM Software Group.

In 2004, Frank Leymann was appointed full professor of computer science at the University of Stuttgart, where he founded the Institute of Architecture of Application Systems and is director of the same. His research interests include middleware in general, pattern languages, and cloud computing, with a current strong focus on quantum computing.

Frank is an elected member of the Academy of Europe (Academia Europaea). He published uncountable papers in journals and proceedings, co-authored four textbooks, and holds more than 70 patents, especially in the area of workflow management and transaction processing. He served on steering-, program- and organization committees of many international conferences, and is (associated) editor of several journals.

From 2006 to 2011, he was a member of the scientific directorate of Schloss Dagstuhl (Leibniz Center of Computer Science). In 2019, he was appointed as a Fellow at the Center of Integrated Quantum Science and Technology (IQST), and in 2020 he was appointed as Member of the Expert Council for Quantum Computing of the German Government.

About Johanna Barzen

Johanna Barzen is leading the Quantum Computing and Digital Humanities research area at the Institute of Architecture of Application Systems (IAAS), University of Stuttgart. Currently she is also a visiting scientist at the Business Informatics Group of the TU Wien Informatics, bridging the research areas model-driven development and digital humanities. Her research lies in the intersection of computer science, media science, digital humanities, and quantum computing. Thereby, she applies pattern languages, data analytics, and machine learning.

From 2012 on she is working on digital humanities projects and developed the MUSE method along with a supporting tool chain to identify costume pattern languages in films. Her interdisciplinary approach of combining research on digital humanities with the potentials of quantum computing coined the term Quantum Humanities. Ongoing research on (quantum) machine learning is currently determining the potentials of quantum approaches in contrast to classical approach.


With Frank Leymann, full professor of computer science at the University of Stuttgart, Germany, and one of the highest-ranked computer scientists in the world, we launched our Kurt Gödel Visiting Professorship at TU Wien Informatics.

We invite highly renowned scientists to serve as Kurt Gödel Visiting Professors to further our international outreach and cooperation. This high-level exchange ensures excellence in science and lively collaboration with our professors’ universities.

Kurt Gödel Visiting Professors are appointed for three years. They are teaching and pursuing research with students and scientists at TU Wien Informatics.
