Date and time: Tuesday 8:15-10:00 Thursday 8:15-10:00
Tutorials: We offer three tutorials. Hand in the homework in the tray in front of room 0.1.01. The deadline for the submission of the exercises is agreed upon with the tutor of each tutorial. You can also mark the questions you would like to have corrected and marked in detail.
Monday 14-16, room 1.1.53
Monday 16-18, room 1.4.31
Tuesday 16-18, room 1.1.16
The tutors are Clara Wassner, Simon Cichy, Yifan Tang, Jacopo Rizzo. We have decided to hold one tutorial on 22.04 16-18 in room 1.1.16 introducing regulations and answering questions. We will discuss exercise sheets from the week starting on 28.04.
Problem sheets: The exercise sheets will be made available here.
This course provides an overview of an exciting emerging field of research, that of quantum information theory. The field is concerned with the observation that single quantum systems used as elementary carriers of information allows for entirely new modes of quantum information processing and communication, quite radically different from their classical counterparts. Quantum key distribution suggests to communicate in a fashion, secure from any eavesdropping by illegitimate users. Quantum simulators can outperform classical supercomputers in simulation tasks. The anticipated - but now rapidly developing - devices of quantum computers can solve not all, but some delicate computational problems that are intractable on classical supercomputers. This course will give a comprehensive overview over these developments. At the heart of the course will be method development, setting the foundations in the field, building upon basic quantum theory. We will also make the point that quantum information is not only about information processing, but a mindset that can be used to tackle problems in other fields, most importantly in consensed matter research, with which quantum information is much intertwined for good reasons.
