Entanglement Renormalization: from Quantum Circuits to Topological Order
I will describe a renormalization group transformation for strongly
correlated quantum systems in D spatial dimensions based on ideas from
quantum computation and quantum information (quantum circuits, entanglement,
...). Entanglement renormalization can be used to study extended quantum
systems in a symmetry breaking phase, as well as quantum phase transitions
between two such phases [cond-mat/0512165, quant-ph/0610099]. Recently it
has been realized that it also offers a natural framework to describe
systems with topological order. I will attempt to present an overview of
these results directed to a mixed audience of researchers in theoretical
quantum computation/information and condensed matter.
