Abstract: This work deals with percolation in coined quantum walks. We use the model of percolation known from classical physics as an example of disturbance in quantum walks.  After some introduction to the percolation process we summarize some published results mainly about spreading of a quantum walk on an infinite percolated graph. In the second part we utilise findings about random unitary operators for finding the long-term behaviour of percolated quantum walks on finite graphs. The main part of this work is finding possible asymptotic states for partially percolated quantum walk on two particular finite graphs.
