Long-distance entanglement and quantum teleportation in coupled cavity arrays
Salvatore M. Giampaolo, Fabrizio Illuminati
We introduce quantum spin models whose ground states allow for sizeable entanglement between distant spins. We discuss how spin models with global end-to-end entanglement realize q…

Separability and ground state factorization in quantum spin systems
S. M. Giampaolo, G. Adesso, F. Illuminati
We investigate the existence and the properties of fully separable (fully factorized) ground states in quantum spin systems. Exploiting techniques of quantum information and entang…
