The theory of entanglement has provided a new language to describe interacting quantum many
body systems, opening up new possibilities in determining static and dynamical properties of such
systems. This proposal aims at using the theory of entanglement and more specifically the theory of
tensor networks to simulate gauge theories. The big advantage of this method is the fact that tensor
networks do not suffer from the sign problem, thereby giving access to properties and quantitites
not accessible by quantum Monte Carlo methods. It also provides a new ways of constructing order
parameters for topologically ordered phases and of characterizing elementary excitations. We will
focus on studying gauge theories in 2+1 dimensions, which is a territory as yet almost untouched
upon by tensor network methods, and open up the way of simulating gauge theories in 3+1
dimensions.
