Andrzej Grudka, Pawel Kurzynski
It was presented by Cabello and Nakamura [A. Cabello, Phys. Rev. Lett. 90, 190401 (2003)], that the Kochen-Specker theorem applies to two dimensions if one uses Positive Operator-V…

Malgorzata Bednarska, Andrzej Grudka, Pawel Kurzynski +2
In the note we show how the choice of the initial states can influence the evolution of time-averaged probability distribution of the quantum walk on even cycles.
