Optimal electron propagation on a quantum chain by a topological phase
S. Paganelli, G. L. Giorgi, F. de Pasquale
We study the quantum diffusion of an electron in a quantum chain starting from an initial state localized around a given site. As the wavepacket diffuses, the probability of recons…

Some features of the state-space trajectories followed by robust entangled four-qubit states during decoherence
A. P. Majtey, A. Borras, A. R. Plastino +2
In a recent work (Borras et al., Phys. Rev. A {\bf 79}, 022108 (2009)), we have determined, for various decoherence channels, four-qubit initial states exhibiting the most robust p…
