The aim of the course is to introduce the fundamental ideas, concepts and principles that are used to analyze information and quantum information through algorithms based on information theory and quantum mechanical mathematical principles.
Additionally the course will generally develop the student's ability to assimilate and communicate mathematical theory and use it in conjunction with other areas, such as information technology and computer science, to build a new generation of efficient algorithms and to solve problems theoretically and using the computer. In addition the course shall enhance students' knowledge of mathematical programming and computational techniques, and their abilities for independent analysis of mathematical models and solution of mathematical problems.
After completing the course, students should be able to
- explain and compare main examples and fundamentals for classical- and quantum information
- explain ideas, principles and mathematical models which underlie secure and reliable transmission of information and classical and quantum cryptography
- describe and use different types of quantum gates in their matrix representation and input-output signal system presentation, as well as understand principles for construction and presentation of quantum circuits and quantum algorithms in matrix and in system forms
- provide and explain the examples and basics of the theory of quantum operations, and apply techniques of linear algebra, geometry of linear transformations and factorizations of matrices for construction of more complex quantum operations from the elementary quantum operations
- explain the use of matrix norms and vector norms for estimating computational errors in quantum circuits as well as explain basic ideas, theory and examples of error correcting codes
- explain the difference in complexity between quantum algorithms and classical algorithms, as well as explain why some quantum algorithms are significantly more efficient than the known classical ones
- explain the basic ideas as well as the mathematical principles behind quantum cryptography algorithms, and describe the most important examples of applications of quantum cryptography

A student who has a certificate from MDH regarding a disability has the opportunity to submit a request for supportive measures during written examinations or other forms of examination, in accordance with the Rules and Regulations for Examinations at First-cycle and Second-cycle Level at Mälardalen University (2016/0601). It is the examiner who takes decisions on any supportive measures, based on what kind of certificate is issued, and in that case which measures are to be applied.
Suspicions of attempting to deceive in examinations (cheating) are reported to the Vice-Chancellor, in accordance with the Higher Education Ordinance, and are examined by the University’s Disciplinary Board. If the Disciplinary Board considers the student to be guilty of a disciplinary offence, the Board will take a decision on disciplinary action, which will be a warning or suspension.
No specific environmental aspects are included in this course.
Course literature is preliminary until 3 weeks before the course starts. Literature may be valid over several terms.
