Trapping a particle of a quantum walk on the line
Antoni Wojcik, Tomasz Luczak, Pawel Kurzynski +3
We observe that changing a phase at a single point in a discrete quantum walk results in a rather surprising localization effect. For certain values of this phase change the possib…
Discrete Time Quantum Walk Approach to State Transfer
Pawel Kurzynski, Antoni Wojcik
We show that a quantum state transfer, previously studied as a continuous time process in networks of interacting spins, can be achieved within the model of discrete time quantum w…
Comment on "Information flow of quantum states interacting with closed timelike curves"
Waldemar Klobus, Andrzej Grudka, Antoni Wojcik
We show that recent results on the interaction of causality-respecting particles with particles on closed timelike curves derived in [Phys. Rev. A 82, 062330 (2010)] depend on ambi…
