Mesoscopic continuous and discrete channels for quantum information transfer
F. de Pasquale, G. Giorgi, S. Paganelli
We study the possibility of realizing perfect quantum state transfer in mesoscopic devices. We discuss the case of the Fano-Anderson model extended to two impurities. For a channel…
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…
A new expansion around mean field for the quantum Ising model
F. De Pasquale, S. M. Giampaolo
We show that an high temperature expansion at fixed order parameter can be derived for the quantum Ising model. The basic point is to consider a statistical generating functional a…
Quantum computing in a Spin ordered phase
F. de Pasquale, S. M. Giampaolo
We show that quantum computation can be performed in a system at thermal equilibrium if a spontaneous symmetry breaking occurs. The computing process is associated to the time evol…
