Abstract
Using the concept of von Neumann entropy, we quantify the information content of the various components of the quantum walk system, including the mutual information between its subsystems (coin and position) and use it to give a precise formulation of the measure of entanglement between subsystems.

It will be interesting to consider basic quantities of information theory to give a precise formulation of the measure of entanglement between subsytems (coin and position)
