I will be using the kwant software package (www.kwant-project.org). It is written in python, so please learn python! This should be very easy for anyone with some programming knowledge. I can recommend http://www.diveintopython.net/ as a good source, but searching the internet will give you tons of learning resources.
If you want to prepare very thoroughly for the lecture, I would advise you to learn the concepts of the scattering matrix and quantum transport, as well as tight-binding Hamiltonians (covered for example in [1], but this will also briefly be surveyed in the first lecture). Also, there is an extensive tutorial for the kwant software package on www.kwant-project.org.
