Matrix product states with long-range localizable entanglement
Thorsten B. Wahl, David Pérez-Garcı́a, J. I. Cirac · Physical Review A · 2012
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.
