Lecturer: Ronald de Wolf (CWI and ILLC)

Teaching assistants: Joran van Apeldoorn in the first half of the course, Andras Gilyen in the second half (both are PhD students at CWI)

This course will complement Maris Ozols and Michael Walter's course on Quantum Information Theory that's taught on Monday afternoon. Neither course requires the other, but students interested in writing a thesis in quantum computation/information are encouraged to follow both.

Each Monday block consists of 2 hours of lectures followed by an exercise session.

Mastermath will record the lectures.

- The homework needs to be handed in before the start of the next lecture, i.e., the next Monday 10:00, in person or by email to
**homeworkquantumcomputing@gmail.com**. This is a**hard deadline**: if you arrive late for the lecture, then you cannot hand in homework anymore, similarly if you send it by an email that arrives after 10:00. - The answers should be in English. Handwritten solutions or emailed scans thereof are fine, as long as they are clearly readable. If you're emailing your solutions, please send a (moderately-sized)
**pdf attachment**, not separate images (nor a url); the contrast should be sufficient so that it's still readable after printing ("CamScanner" is a decent app for this). - Cooperation among students is allowed, but everyone has to hand in their own solution set in their own words. Do not share files before the homework deadline, and never put the solutions online. Plagiarism will not be tolerated.
- Note that Appendix C has hints for some of the exercises, indicated by (H). If you have questions about the homework or the lectures, email Ronald (rdewolf@cwi.nl).

Here are our notes with general feedback on the homework, incl. some model solutions. These notes will be updated every week, so check them regularly.

Final exam (open book: all paper is allowed, no electronics)

Location: REC C1.104 (Roeterseiland)

If you want to practice, here are the exams from 2015, 2017, and 2018, with solutions.

- Monday July 15, 10:00-13:00

Re-sit of the exam (open book: all paper is allowed, no electronics)

Location: Science Park B0.207

If you want to take the re-sit: let Ronald know by email, at least one day in advance. If you take the re-sit, the earlier exam-grade will be nullified and replaced by the re-sit-grade. Be aware that this could actually worsen your grade, or even make you fail the course if your re-sit grade is <5.0. Your homework grade will still count for 40%.
