Long-distance entanglement and quantum teleportation in coupled-cavity arrays
S. M. Giampaolo, Fabrizio Illuminati · Physical Review A · 2009
We introduce quantum spin models whose ground states allow for sizable 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.
