Many recent developments in the theory of quantum information have led to
important insights and applications in condensed matter physics. For
instance, the theory of entanglement has shed new light on the density
matrix renormalisation and the real space renormalization numerical methods,
culminating in a deeper understanding of the strengths of the methods and
applications to a wider class of problems including critical systems and
systems in more than one spatial dimension. Similarly, the theory of quantum
error correction has led to new classes of theoretical models of interacting
particles that exhibits topological order, an exotic phase of matter where
excitation can have non-Abelian statistics. The study of information
propagation in a system of interacting particles was used to prove the
existence of an entanglement entropy area law in the ground state of systems
with local interactions. The problem of finding ground states of a system
composed of interacting particles was proven to be complete for the
complexity class QMA, the quantum analogue of NP. These are just a few
examples illustrating the connections between quantum information and
condensed matter physics.

The purpose of this workshop will be to bring together some of the world's
leading experts in quantum information and condensed matter physics with
interests in the connections between the two fields. This will represent a
opportunity to deepen our understandings of the connections between these
fields and to tackle important open questions such as the quantum analogue
of the probabilistically checkable proof (PCP) theorem and the existence of
self-correcting phases of matter.
