Course objectives

Upon completion of this course you will be able to:

  • understand the essential aspects of a modern research publication in the field of quantum computation.

Schedule

The timetables are available through My Timetable (see the button in the upper right corner).

Teaching method

See Brightspace

Assesment method

The final grade will be determined as follows:

  • Final exam (100%)

Resit, review & feedback

Examinations are held twice during the academic year for each component offered in that academic year. Midterm tests cannot be retaken. The Board of Examiners determines the manner of resit for practical assignments.
For review and feedback, see Brightspace.

Software
Starting from the 2024/2025 academic year, the Faculty of Science will use the software distribution platform Academic Software. Through this platform, you can access the software needed for specific courses in your studies. For some software; your laptop must meet certain system requirements; which will be specified with the software. It is important to install the software before the start of the course. More information about the laptop requirements can be found on the student website.
