# Quantum Processes and Computation

## NWI-IMC055, Spring 2019

This page contains specific information about the **Spring 2019** course and lectures (for general information, see studiegids). All relevant course information will be provided here (and not in Brightspace).

For exercises, see the: **exercise page**.

**Prerequisites** consist of linear algebra and some basic familiarity with definition/lemma/theorem-style mathematical reasoning.

**Course material** consists of:

- Slides for some lectures (see below)
- Lecture notes (available on Brightspace)
- Textbook: Picturing Quantum Processes: A First Course in Quantum Theory and Diagrammatic Reasoning

The textbook is available in the science library (but possibly only 1 copy!), and students may purchase it if they wish. The lecture notes contain the same material, and in cases where there are discrepancies (e.g. with exercise numbering), I will try to stick to the lecture note version.

**Lectures** will be given by Aleks Kissinger and John van de Wetering in English. All course materials will be in English.

- Lectures will be on
**Wednesdays 15:30-17:15**in HG01.028. - First lecture:
**January 30** - Last lecture:
**June 5** - The will be NO LECTURES on
**March 20**,**March 27**,**April 3**, and**May 1**. **Werkcollege's**take place on**Thursdays 15:30-17:15**, from January 31 until June 6. They are in a different room each week, so please check the schedule.*In weeks with no lecture, there will also be no werkcollege. There are also NO WERKCOLLEGE'S on***April 18**and**May 30**.- There is a
**Practicum**on**June 3**in HG00.206.

## Grading and Administration

- Lectures, werkcollege's and homework are not mandatory. However, homework (
*H*) assignments will be graded weekly and will provide up to 1 bonus point on the final grade. - There will be a larger take-home coursework (
*C*) due after the mid-semester break. This assignment**is**mandatory, and must be done individually (not in groups). It will constitute 20% of your final grade. - There will be a lab session (
*L*) using the tool Quantomatic in the 4th quarter. Participation and write-up will constitute 10% of your grade. - The remaining 70% of your final grade will be from a written exam (
*E*), taking place after the end of the course. - In summary, final grades are calculated as:
*F = 0.7 * E + 0.2 * C + 0.1 * L + 0.1 * H*To pass,

*E*must be at least 5 and*F*must be at least 6.
