Introduction to Quantum Information and Quantum Computation

With the knowledge that quantum mechanics is intimately involved with probability theory, development of information theory and operator theory led to the realisation of quantum information theory and quantum computing. You can Google it a qbit at a time.

Information for admitted students Spring 2021

Congratulations! You have been admitted at Stockholm University and we hope that you will enjoy your studies with us.

In order to ensure that your studies begin as smoothly as possible we have compiled a short checklist for the beginning of the semester.

Follow the instructions on wether you have to reply to your offer or not.


Checklist for admitted students

  1. Activate your university account

    The first step in being able to register and gain access to all the university's IT services.

  2. Register at your department

    Registration can be done in different ways. Read the instructions from your department below.

  3. Read all the information on this page

    Here you will find what you need to know before your course or programme starts.


Your seat may be withdrawn if you do not register according to the instructions provided by your department.

Information from your department

On this page you will shortly find information on registration, learning platform, etc.

Welcome activities

Stockholm University organises a series of welcome activities that stretch over a few weeks at the beginning of each semester. The programme is voluntary (attendance is optional) and includes Arrival Service at the airport and an Orientation Day, see more details about these events below.
Your department may also organise activities for welcoming international students. More information will be provided by your specific department. 

Find your way on campus

Stockholm University's main campus is in the Frescati area, north of the city centre. While most of our departments and offices are located here, there are also campus areas in other parts of the city.

Pre-departure information

New in Sweden

The course covers the rapidly expanding research field of quantum information and quantum computation. The course provides an information theoretic approach to basic laws of quantum physics. We will start by looking at basic quantum mechanics, including quantum entanglement and quantum measurement. We will then introduce classical information theory and its generalization to quantum information, and onto quantum channels and quantum cryptography. We then look at quantum computing, focussing on quantum gates and elementary quantum circuits, quantum algorithms, and quantum error correcting codes. Finally, the recent physical realizations of quantum computers will be addressed.

Teaching during the spring semester 2021

During the spring semester 2021, lectures will be given remotely. A demonstration/experiment is planned to be carried out on campus. The course will be examined through written home assignments.

More information about the course can be found on the course page.

  • Course structure

    This is a second cycle course given at half speed during daytime. This course can also be taken as a third cycle course.

    Teaching format

    The teaching consists of lectures, one practical session, and problem solving exercises.


    The course is examined continual assessment through home exercises supplemented with hand-in problems at the end of the course.

  • Schedule

    The schedule will be available no later than one month before the start of the course. We do not recommend print-outs as changes can occur. At the start of the course, your department will advise where you can find your schedule during the course.
  • Course literature

    Note that the course literature can be changed up to two months before the start of the course.
