Frank Leymann, first Kurt Gödel Visiting Professor at TU Wien Informatics, gave an introduction to quantum computing.

The Power of Quantum Computing

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 on 19 April 2021.

In case you missed Frank Leymann’s lecture “The Power of Quantum Computing”, you can watch it on YouTube.

By inviting renowned international scientists like Frank Leymann to serve as Kurt Gödel Visiting Professors, we wish to further our global outreach and cooperation. This high-level exchange ensures excellence in science and lively collaboration with our professors’ universities. Since they teach and pursue research with students and scientists at TU Wien Informatics, this exchange is very beneficial for our students, as Dean Gerti Kappel emphasized in her welcome address.

The Limits of Classical Computing

In his lecture, Frank Leymann pointed out that classical computer technology is reaching its limits soon. Quantum computing is perceived to have a profound impact on computing and society in general. In this talk, Frank Leymann presented the underpinnings of quantum computing. The notion of quantum bits and phenomena like quantum parallelism and entanglement—which are considered to be the sources of the power of quantum computers—were explained.

He also introduced how quantum computers are programmed, which is very different from programming classical computers. The potentials of quantum computers were exemplified by sketching how factorization is done exponentially faster, impacting today’s security infrastructure. Finally, Frank Leymann illustrated the limits of currently available quantum computers.

About Frank Leymann

Frank Leymann, our first Kurt Gödel Visiting Professor, was born in Bochum in 1957. He 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 comprise service-oriented computing and middleware, workflow- and business process management, pattern languages, cloud computing, transaction processing, integration technology, and 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 close to 60 patents, especially in the area of workflow management and transaction processing. He served on 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 accepted as a Fellow at the Center of Integrated Quantum Science and Technology (IQST).
