Lecture notes for the summer term 2025

Welcome

These are the lecture notes for the “Introduction to Quantum Computing” lecture held by Dominique Unruh at RWTH Aachen in the summer term 2025. They should be viewed as an addition to the handwritten notes and the lecture recordings.

The lecture notes will be updated progressively throughout the semester, following the pace of the lectures. Last year’s lecture notes can be found here, but note that they are incomplete and may differ from this years content.

If you prefer a .pdf file, there is a download available at the top left corner. An .epub version is being worked on.

If you spot an error, please report it to Gitlab. Alternatively, you can send Stefan Stump an e-mail (stefan.stump@rwth-aachen.de).If you have a question of understanding, please ask it in the Moodle forum.

These lecture notes are released under the CC BY-NC 4.0 license, which can be found here.

The Jupyter notebooks created during the lectures can be found in the JupyterHub in the course “[IQC] Introduction to Quantum Computing” or in Moodle. These will be added shortly after the lectures. If changes are made to the files, they can be easily reset with the usual git commands using “Git” and then “Open Git Repository in Terminal.
