Transfiguration of Quantum Walks on a line
Mahesh N. Jayakody, Asiri Nanayakkara
We introduce an analytically treatable spin decoherence model for quantum walk on a line that yields the exact position probability distribution of an unbiased classical random wal…

Full state revivals in higher dimensional quantum walks
Mahesh N. Jayakody, Asiri Nanayakkara
Full state revivals in a quantum walk can be viewed as returning of the walker to the initial quantum state in a periodic fashion during the propagation of the walk. In this paper…

Reversion of Quantum Walks via interventions on coin space
Mahesh N. Jayakody, Asiri Nanayakkara
In this study we show a way of achieving the reverse evolution of n-dimensional quantum walks by introducing interventions on the coin degree of freedom during the forward progress…
