**exclusively** in presence. Lecture recordings (in German) of the last terms can be found in LMUCast (link to playlist is in the

Moodle course).

### Content of the Lecture

Two scientific revolutions shaped the first half of the 20th century. On the one hand, pioneers such as Konrad Zuse, Alan Turing, and John von Neumann laid the foundations for the construction of the first practical calculating machines. On the other hand, the classical world view of physics, which had been expanded but hardly changed since the days of Newton, collapsed with the description of quantum mechanics.

These scientific revolutions were quickly followed by technical ones. Everyone is aware of the extent to which computers have shaped our society, our view of the world and our view of humanity. Many people are less aware that quantum mechanics also influences our everyday lives. It was the quantum mechanical description of the atom that made it possible to develop semiconductors and lasers; the transistor radio, the CD player and modern computer hardware are all consequences of quantum mechanics.

In recent decades, these two sciences have been brought together and a new interdisciplinary branch called quantum computing has emerged. The aim is to build quantum computers, develop quantum algorithms and investigate the consequences of quantum mechanics for information transmission.

The lecture explains the basics of quantum computing, including:

- Introduction to quantum mechanics
- Mathematical foundations (mainly linear algebra)
- Complexity of quantum algorithms and the need for new complexity classes
- Quantum bits (qubits) and quantum registers
- Quantum teleportation, dense coding and entanglement
- Various quantum algorithms, including search algorithms and quantum Fourier transformations
- Shor's algorithm and the implications for modern cryptography
- Hybrid quantum algorithms
- Quantum communication and quantum cryptography
- Available hardware and quantum computers

In the tutorials, this knowledge will be deepened and quantum algorithms will be implemented independently.
These are carried out with a simulator, but also with a real quantum computer (IBM-Q).

### Prior Knowledge

**To participate, you should be familiar with the following content:**

- Linear algebra
- Cryptography (e.g. from the IT security lecture): symmetric and asymmetric encryption methods (e.g. RSA), key exchange (e.g. Diffie-Hellmann)
- Basic understanding of quantum physics is helpful, but not a prerequisite

### Participation

**Audience:**The lecture is aimed at students in the Master's degree program in Computer Science, Media Informatics, Bioinformatics, students in the main study program in Computer Science (Diploma) or Media Informatics (Diploma) as well as students with a minor in Computer Science.
Bachelor's students of Computer Science or Media Informatics can specify the lecture as "Vertiefende Themen der Informatik für Bachelor".
**SWS/ECTS:** 5 SWS (3V, 2Ü), 6 ECTS according to module description
**Major course assessment:** Written exam
**Exercise mode:** In addition to the lecture, weekly exercise sheets with tutorials are offered, with the submission of exercise sheets a bonus can be earned for the exam.
