NFYK23005U Physical Implementations of Quantum Information Processing
MSc Programme in Nanoscience
MSc Programme in Physics
MSc Programme in Quantum Information Science
Quantum information processing aims at exploiting the laws of quantum mechanics to solve tasks which are impossible with the technologies we have to day. To realise these applications, it is essential to make devices capable of processing information according to the laws of quantum mechanics. The aim of this course is to give an introduction to how to build such quantum information processors, both for quantum computation and quantum communication. To this end, we will study some of the leading platforms used in the field today. We will discuss the basic principles of the platforms and where they are today, as well as their imperfections and the challenges facing them.
Skills
After the course, the student should be able to describe how quantum information processing is implemented in various systems as well as their challenges and imperfections. Specifically the student should be able to:
- Describe imperfections with the density matrix and master equation.
- Explain how to realise quantum computation with trapped ions, superconducting qubits and spin qubits in gate defined quantum dots.
- Explain simple quantum communication protocols, e.g. quantum repeaters, and how they are realised with atomic ensembles, NV centers and self-assembled quantum dots.
- Discuss advantages and disadvantages of the various systems considered as well as the challenges facing them.
- Be familiar with basic experimental techniques used for quantum information processing.
Knowledge
The participants should know how one can implement quantum information processing in physical systems. Specifically, the students should know this for the systems mentioned above. Furthermore, they should know the status of current research in the field and how far we are in building quantum information processors.
Competences
After the course, the student will be familiar with state-of-the-art experiments in quantum information processing. Throughout the course, we will read scientific articles reporting progress on real implementations. This will give the students experience with reading original scientific literature. In addition the students will acquire tools to describe open quantum systems and understand imperfections in real implementations. The combination of these things will give the participants a firm background for a possible master thesis on the implementation of quantum information processing.
