Relative homotopy approach to topological phases in quantum walks
Andrzej Grudka, Marcin Karczewski, Pawel Kurzynski +2
Discrete-time quantum walks (DTQWs) provide a convenient platform for a realisation of many topological phases in noninteracting systems. They often offer more possibilities than s…

Complementarity in quantum walks
Andrzej Grudka, Pawel Kurzynski, Tomasz P. Polak +3
We study discrete-time quantum walks on -cycles with a position and coin-dependent phase-shift. Such a model simulates a dynamics of a quantum particle moving on a ring with an…
