Long-distance entanglement and quantum teleportation in coupled cavity arrays
arXiv:0906.2801 · doi:10.1103/PhysRevA.80.050301
Abstract
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 quantum teleportation channels with optimal compromise between scalability and resilience to thermal decoherence, and can be implemented straightforwardly in suitably engineered arrays of coupled optical cavities.
