Localization properties and high-fidelity state transfer in electronic hopping models with correlated disorder
Guilherme M. A. Almeida, Caio V. C. Mendes, Marcelo L. Lyra +1
We investigate a tight-binding electronic chain featuring diagonal and off-diagonal disorder, these being modelled through the long-range-correlated fractional Brownian motion. Par…
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…
