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 records the lectures: here's the link, with password yjD3

- 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 the hint gives you some facts (for instance that there exists an efficient classical algorithm for testing if a given number is prime) then you can use these facts in your answer without proving/deriving these facts themselves.
- If you have questions about the homework or the lectures, email Ronald (rdewolf@cwi.nl).
- You can pick up your graded homework in subsequent lectures.

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.

The final exam (June 24) will be open book, meaning you can bring the lecture notes, your own notes, homework, and any other papers you want, but no electronic devices. Your grade for the exam should be at least 5.0 in order to pass the course. There's the possibility for a re-sit of the exam on July 15. The final grade is determined for 60% by the final exam (or the re-sit if you take it) and 40% by the homework-grade. In accordance with the Mastermath rules, the final grade will be rounded to the nearest integer, also for Master of Logic students.

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

Location: REC C1.04 (Roeterseiland)

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

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%.
