Introduction to open quantum systems -- spring term 2015
Lecturers
Course Description
The ability to manipulate objects on the smallest scales is ever increasing. To understand the physical basis of quantum computing and other exciting new technologies we must go beyond knowing the building blocks of nature (electrons, atoms, quantum dots etc) by themselves: we have to understand how they interact with the rest of the world. The objective of the course "Introduction to open quantum systems" is to do precisely this, with a focus on the physical process of decoherence. Topics covered in the course include the Feynman-Vernon theory of a quantum system interacting with a bath modelled as a large set of harmonic oscillators, quantum jump phenomena, and an interaction to experimental research in the Low Temperature Laboratory and Department of Applied Physics at Aalto.We will follow the text book of Breuer and Petruccione, available in Aalto library.
More information available in Noppa and Oodi by the course code PHYS-E0542. The course is given jointly by Aalto University and University of Helsinki.
