Localization in Quantum Walks with a Single Lattice Defect: A Comparative Study
Laurita I. da S. Teles, Edgard P. M. Amorim
We study how a single lattice defect in a discrete time quantum walk affects the return probability of a quantum particle. This defect at the starting position is modeled by a quan…
Quantum Corralling
Rafael Vieira, Gustavo Rigolin, Edgard P. M. Amorim
We propose a robust and efficient way to store and transport quantum information via one-dimensional discrete time quantum walks. We show how to attain an effective dispersionless…
Trojan Quantum Walks
Henrique S. Ghizoni, Edgard P. M. Amorim
We investigate the transport properties and entanglement between spin and position of one-dimensional quantum walks starting from a qubit over position states following a delta-lik…
Connecting velocity and entanglement in quantum walks
Alexandre C. Orthey, Edgard P. M. Amorim
We investigate the relation between transport properties and entanglement between the internal (spin) and external (position) degrees of freedom in one-dimensional discrete time qu…
On the spreading of quantum walks starting from local and delocalized states
Alexandre C. Orthey, Edgard P. M. Amorim
We investigate the ballistic spreading behavior of the one-dimensional discrete time quantum walks whose time evolution is driven by any balanced quantum coin. We obtain closed-for…
