Multiuser quantum communication networks
A. Wojcik, T. Luczak, P. Kurzynski +3
We study a quantum state transfer between spins interacting with an arbitrary network of spins coupled by uniform XX interactions. It is shown that in such a system under fairly ge…
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.
Quantum walks on cycles
Malgorzata Bednarska, Andrzej Grudka, Pawel Kurzynski +2
We consider asymptotic behaviour of a Hadamard walk on a cycle. For a walk which starts with a state in which all the probability is concentrated on one node, we find the explicit…
