Quantum Information

Text book

John Preskill, Quantum Information chapters 1-6 and chapter 7
additional background material (with updates to some of the chapters in Preskill)

Preskill's book provides background and context to the material covered in the lectures and exercise classes. It also contains much additional material that goes beyond the course and will not be examinated.
Exercises

problem sets 1-9
The exercise classes are the most important part of the course, and the three problem sets are representative for the written exam. Two problems in each set are marked as "homework". You are requested to submit your detailed solution of these two problems to the course assistants at the start of the class, who will then grade each with "pass" or "fail". Each "pass" gives you 1/6 of a bonus point for the written exam on 18 November, 2022.
