Simulating strongly correlated quantum systems have always been a
challenge in computational physics. Because of the sign problem
generically present in the Monte-Carlo simulation of the physics,
it is not enough to look for clever algorithms. Recently, the
development in the field of quantum optics, have provided yet
another toolbox to use in the study of such systems:
quantum simulation. In this talk, we will discuss how such an
approach can be used to study questions of interest in gauge
theories, particularly in lattice gauge theories. As an example
of an Abelian gauge theory, the Schwinger model in (1+1)-D will
be used to outline the study of string dynamics. Non-Abelian models
can also be studied with an aim to study the real-time dynamics of
chiral symmetry breaking. The procedure of realizing these theories
as the low-energy limit of Hubbard-type models set up on optical
lattices will be discussed.
