Entry requirements

120 credits in science/engineering. Participation in Quantum Mechanics, Advanced Course. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On completion of the course, the student should be able to:

• in words explain central theoretical concepts in quantum information,
• analyse quantum states by using tools in quantum information theory,
• solve problems in quantum information,
• describe possible applications of quantum information in information technology.

Content

Density operators, projective and generalised measurements, no-cloning theorem, quantum copying, open quantum systems: Lindblad's equation

Qubits: physical realisations and the Bloch sphere, quantum entanglement, quantum teleportation

Quantum key distribution

Entropy (von Neumann), distance measures for quantum information: trace distance and fidelity

Completely positive maps, Kraus representations

Applications such as quantum computers and quantum cryptography.

Instruction

Lectures, exercise classes and supervision of projects.

Assessment

Written exam (4 credits), project with oral presentation (1 credit).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
