Matrix Product States with long-range Localizable Entanglement    [PDF]

Thorsten B. Wahl, David Perez-Garcia, J. Ignacio Cirac

We derive a criterion to determine when a translationally invariant matrix product state (MPS) has long-range localizable entanglement, where that quantity remains finite in the thermodynamic limit. We give examples fulfilling this criterion and eventually use it to obtain all such MPS with bond dimension 2 and 3.
