Teaching

Lecturer of the supplementary lectures
  • Summer Semester 2025
  • Summer Semester 2026
Content

The basic concepts and techniques of quantum computing (i.e., quantum computing and quantum information) are understood, and the necessary tools from physics and mathematics are known. Quantum bits and quantum registers are understood, and essential register operations as the basis of a quantum assembler are clear. The meaning of entangled states is clear. Basic algorithms (Deutsch-Jozsa, Shor, Grover) and their representations are understood. The role of measurement and the basic structure of quantum algorithms are clear. Fundamental properties of quantum information such as teleportation, superdense coding, or no-cloning, and also the information content of qubits are recognized. The meaning of decoherence is understood, the main types of errors and their correction possibilities are clear, the basics of error tolerance are clarified.

Lecturer
  • Winter Semester 2025/2026
  • Summer Semester 2026
Content

This seminar is aimed at students who want to deepen their knowledge of quantum informatics. The focus is on selected, current research topics that are particularly relevant for the practical implementation and further development of quantum computers.

One focus is, among other things, on quantum error correction and the analysis of variational quantum algorithms.

Lecturer
  • Winter Semester 2025/2026
Content

This seminar offers a hands-on and theoretical introduction to the world of Cloud Computing (CC). It is aimed at students who want to understand how quantum computers are made accessible today via cloud platforms and what opportunities and challenges are associated with them. Participants will gain an overview of cloud computing in general, including architecture, service models (IaaS, PaaS, SaaS), and virtualization technologies, to lay the foundation for accessing quantum resources. Building on this, the special requirements of quantum computing in the cloud will be examined: remote access to quantum hardware and hybrid workflows.

A particular focus is on the practical use of existing platforms such as IBM, Amazon Braket, or Microsoft Azure Quantum. Participants will work with real quantum computers in the cloud, conduct simple experiments, and analyze their results.

Tutor
  • Summer Semester 2024
  • Summer Semester 2025
Content

In data structures and algorithms, you learn how data can be stored, organized, and processed efficiently. This includes basic data structures like lists, stacks, queues, trees, and graphs, as well as algorithms for searching, sorting, and optimizing. Additionally, you learn how to analyze runtime and memory usage to make programs faster and more efficient.

Tutor
  • Winter Semester 2023/2024
  • Winter Semester 2024/2025
Content

Using the Java programming language as an example, you will be shown the most important concepts of a higher programming language and how to use them. The aim is to teach you how to design, describe and code data and sequence structures so that you can independently analyse, design and implement small programs (up to a few hundred lines) yourself.
