Analytic results on long distance entanglement mediated by gapped spin chains

A. Ferreira, J. M. B. Lopes dos Santos

We give an analytical description of long distance entanglement (LDE) mediated by one-dimensional quantum spin chains recently found in numerical studies. We develop a formalism th…
