Storage of Quantum Coherences as Phase Labeled Local Polarization in Solid State NMR
María Belén Franzoni, Rodolfo H. Acosta, Horacio M. Pastawski +1
Nuclear spins are promising candidates for quantum information processing because their good isolation from the environment precludes the rapid loss of quantum coherence. Many stra…
Perfect state transfers by selective quantum interferences within complex spin networks
Gonzalo A. Alvarez, Mor Mishkovsky, Ernesto P. Danieli +3
We present a method that implement directional, perfect state transfers within a branched spin network by exploiting quantum interferences in the time-domain. That provides a tool…
Decoherence as attenuation of mesoscopic echoes in a spin-chain channel
Gonzalo A. Alvarez, Ernesto P. Danieli, Patricia R. Levstein +1
An initial local excitation in a confined quantum system evolves exploring the whole system, returning to the initial position as a mesoscopic echo at the Heisenberg time. We consi…
Crucial role of decoherence for electronic transport in molecular wires: Polyaniline as a case study
Carlos J. Cattena, Raúl A. Bustos-Marún, Horacio M. Pastawski
In this work we attempt to elucidate the nature of conductivity in polymers by taking the acid-base doped polyaniline (PAni) polymer. We evaluate the PAni conductance by using real…
Controlling the conductance of molecular wires by defect engineering: a divide et impera approach
Daijiro Nozaki, Horacio M. Pastawski, Gianaurelio Cuniberti
Understanding of charge transport mechanisms in nanoscale structures is essential for the development of molecular electronic devices. Charge transport through 1D molecular systems…
