Introduction to decoherence theory short course

This short course of six lectures by Jim Al-Khalili provided an introduction to quantum decoherence and density matrix theory for PhD students starting to work in open quantum systems, quantum optics, quantum information and quantum computing – or indeed for anyone interested in the foundations of quantum mechanics and the famous measurement problem.

The course introduced some of the ideas developed by the likes of Zurek, Zeh, Paz and Joos since the 1970s, but which still find no place in undergraduate courses on quantum mechanics despite their obvious relevance in many areas of physics today, such as quantum optics, quantum information, quantum computing and new theoretical fields such as open quantum systems, quantum thermodynamics and quantum biology.
