Asymptotic entanglement in 1D quantum walks with a time-dependent coined
Asymptotic entanglement 1D quantum walks time-dependent coined
2011/3/3
In this paper we investigate the asymptotic behavior of coin position entanglement (CPE) of a discrete-time quantum walk in one dimensional lattice using a time-dependent unitary coin operator.
Crossovers induced by discrete-time quantum walks
Crossovers induced discrete-time quantum walks
2010/12/15
We consider crossovers with respect to the weak convergence theorems from a discrete-time quan-
tum walk (DTQW). We show that a continuous-time quantum walk (CTQW) and discrete- and
continuous-time ...

Discrete-time quantum walks on one-dimensional lattices
Discrete-time quantum walks one-dimensional lattices
2010/4/2
In this paper, we study discrete-time quantum walks on one-dimensional lattices. We find that the coherent dynamics depends on the initial states and coin parameters. For infinite size of lattice, we ...
