Two-spin entanglement induced by electron scattering in nanostructures
Gian Luca Giorgi, Ferdinando de Pasquale
We present a model where two magnetic impurities in a discrete tight-binding ring become entangled because of scattering processes associated to the injection of a conduction elect…

Diffusive teleportation on a quantum dot chain
F. de Pasquale, G. Giorgi, S. Paganelli
We introduce a model of quantum teleportation on a channel built on a quantum dot chain. Quantum dots are coupled through hopping and each dot can accept zero, one or two electrons…

Double dot chain as a macroscopic quantum bit
F. de Pasquale, G. Giorgi, S. Paganelli
We consider an array of N quantum dot pairs interacting via Coulomb interaction between adjacent dots and hopping inside each pair. We show that at the first order in the ratio of…
