Quantum walks with dynamical control: graph engineering, initial state preparation and state transfer

T Nitsche, F Elster, J Novotný, A Gábris… - New Journal of …, 2016 - iopscience.iop.org
Quantum walks are a well-established model for the study of coherent transport phenomena
and provide a universal platform in quantum information theory. Dynamically influencing the …

[HTML][HTML] Quantum walk transport on carbon nanotube structures

J Mareš, J Novotný, I Jex - Physics Letters A, 2020 - Elsevier
We study source-to-sink excitation transport on carbon nanotubes using the concept of
quantum walks. In particular, we focus on transport properties of Grover coined quantum …

Percolated quantum walks with a general shift operator: From trap** to transport

J Mareš, J Novotný, I Jex - Physical Review A, 2019 - APS
We present an alternative definition of discrete-time coined quantum walks convenient for
capturing a rather broad spectrum of a walker's behavior on arbitrary graphs. It includes and …

Key graph properties affecting transport efficiency of flip-flop Grover percolated quantum walks

J Mareš, J Novotný, M Štefaňák, I Jex - Physical Review A, 2022 - APS
Quantum walks exhibit properties without classical analogues. One of those is the
phenomenon of asymptotic trap**—there can be nonzero probability of the quantum …

Electric quantum walks in two dimensions

LA Bru, M Hinarejos, F Silva, GJ de Valcárcel… - Physical Review A, 2016 - APS
We study electric quantum walks in two dimensions considering Grover, alternate,
Hadamard, and discrete Fourier transform (DFT) quantum walks. In the Grover walk, the …

Strongly trapped two-dimensional quantum walks

B Kollár, T Kiss, I Jex - Physical Review A, 2015 - APS
Discrete time quantum walks (DTQWs) are nontrivial generalizations of random walks with a
broad scope of applications. In particular, they can be used as computational primitives, and …

Discrete time quantum walks on percolation graphs

B Kollár, J Novotný, T Kiss, I Jex - The European Physical Journal Plus, 2014 - Springer
Randomly breaking connections in a graph alters its transport properties, a model used to
describe percolation. In the case of quantum walks, dynamic percolation graphs represent a …

Two-particle Hadamard walk on dynamically percolated line and circle

M Parýzková, M Štefaňák, J Novotný, B Kollár… - Physica …, 2024 - iopscience.iop.org
Asymptotic dynamics of a Hadamard walk of two non-interacting quantum particles on a
dynamically percolated finite line or a circle is investigated. We construct a basis of the …

Complete classification of trap** coins for quantum walks on the two-dimensional square lattice

B Kollár, A Gilyén, I Tkáčová, T Kiss, I Jex, M Štefaňák - Physical Review A, 2020 - APS
One of the unique features of discrete-time quantum walks is called trap**, meaning the
inability of the quantum walker to completely escape from its initial position, although the …
