TSIT13 Quantum Communication
The course takes place throughout the first fall term (HT1) and is an elective course for the Photonics and Quantum Technology profile of the Electrical Engineering and Applied Physics program. It is also taken by Master’s students, Erasmus students and others.
The course aims to an introductory overview of the quantum communication, focusing on theoretical and experimental aspects. The course will teach an overview of quantum key distribution, secret key analysis, entanglement-based quantum communication including teleportation and quantum dense coding. Finally the course will focus on several experimental implementations, giving the student a general view of the field.
The lectures and all literature is in English.
Organisation
There are around 10 two-hour lectures, lessons and lab sessions.

Examination
A written examination three times a year. See the central schedule for examinations.
The examination is based on writing a report on a scientific article related to the topics of the course. It takes place in the exam hall, and the student is given a number of different articles (around five), and chooses one of them to write the report.
