Unmodulated spin chains as universal quantum wires
Antoni Wojcik, Tomasz Luczak, Pawel Kurzynski +3
We study a quantum state transfer between two qubits interacting with the ends of a quantum wire consisting of linearly arranged spins coupled by an excitation conserving, time-ind…

Examples of nonuniform limiting distributions for the quantum walk on even cycles
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.
