Continuous-time quantum walks on a defective lattice: Boosting the spreading of delocalized states through Parrondo's strategy

João V. Cordeiro, Eduardo I. Duzzioni, Edgard P. M. Amorim

We investigate the quantum transport of delocalized states in continuous-time quantum walks (CTQWs) on a one-dimensional lattice containing a single defect. The defect is modeled b…
