Colloquium: Area laws for the entanglement entropy
TL;DR: In this paper, the current status of area laws in quantum many-body systems is reviewed and a significant proportion is devoted to the clear and quantitative connection between the entanglement content of states and the possibility of their efficient numerical simulation.

Entanglement entropy and conformal field theory
Pasquale Calabrese,John Cardy +1 more
TL;DR: In this paper, a conformal field theory approach to entanglement entropy in 1+1 dimensions is presented, and the authors show how to apply these methods to the calculation of the entropy of a single interval and the generalization to different situations such as finite size, systems with boundaries and the case of several disjoint intervals.

Evolution of entanglement entropy in one-dimensional systems
Pasquale Calabrese,John Cardy +1 more
TL;DR: In this paper, the authors studied the unitary time evolution of the entropy of entanglement of a one-dimensional system between the degrees of freedom in an interval of length and its complement, starting from a pure state which is not an eigenstate of the Hamiltonian.

Holographic Entanglement Entropy: An Overview
TL;DR: In this article, the authors review recent progress on the holographic understanding of the entanglement entropy in the anti-de Sitter space/conformal field theory (AdS/CFT) correspondence.
