Quantum Walk on a Line with Absorbing Boundaries
Ammara Ammara, Václav PotoÄek, Václav Potoček +3
Absorption of two-state coined quantum walks on a finite line with two sinks located at and is investigated. Elaborating on the results of Konno et al., J. Phys. A: Math.…

Recurrence in discrete-time quantum stochastic walks
Martin Stefanak, Vaclav Potocek, Iskender Yalcinkaya +2
Interplay between quantum interference and classical randomness can enhance performance of various quantum information tasks. In the present paper we analyze recurrence phenomena i…

Search and state transfer between hubs by quantum walks
Stanislav Skoupy, Martin Stefanak
Search and state transfer between hubs, i.e. fully connected vertices, on otherwise arbitrary connected graph is investigated. Motivated by a recent result of Razzoli et al. (J. Ph…
