Entanglement generation between distant parties via disordered spin chains
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Marcelo L. Lyra
We study the emergence of bipartite entanglement between a pair of spins weakly connected to the ends of a linear disordered spin-1/2 channel. We analyze how their concurrence…
High-fidelity state transfer through long-range correlated disordered quantum channels
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Marcelo L. Lyra
We study quantum-state transfer in spin- chains where both communicating spins are weakly coupled to a channel featuring disordered on-site magnetic fields. Fluctuations…
Disorder-assisted distribution of entanglement in spin chains
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Tony J. G. Apollaro +1
We study the creation and distribution of entanglement in disordered -type spin- chains for the paradigmatic case of a single flipped spin prepared on a fully polarized ba…
