Quantum walk and its application domains: A systematic review

K Kadian, S Garhwal, A Kumar - Computer Science Review, 2021 - Elsevier
Quantum random walk is the quantum counterpart of a classical random walk. The classical
random walk concept has long been used as a computational framework for designing …

Quantum walks: a comprehensive review

SE Venegas-Andraca - Quantum Information Processing, 2012 - Springer
Quantum walks, the quantum mechanical counterpart of classical random walks, is an
advanced tool for building quantum algorithms that has been recently shown to constitute a …

Mobility edges in one-dimensional bichromatic incommensurate potentials

X Li, X Li, S Das Sarma - Physical Review B, 2017 - APS
We theoretically study a one-dimensional (1D) mutually incommensurate bichromatic lattice
system, which has been implemented in ultracold atoms to study quantum localization. It has …

Symmetries, topological phases, and bound states in the one-dimensional quantum walk

JK Asbóth - Physical Review B—Condensed Matter and Materials …, 2012 - APS
Discrete-time quantum walks have been shown to simulate all known topological phases in
one and two dimensions. Being periodically driven quantum systems, their topological …

Topological phases and delocalization of quantum walks in random environments

H Obuse, N Kawakami - Physical Review B—Condensed Matter and Materials …, 2011 - APS
We investigate one-dimensional (1D) discrete-time quantum walks (QWs) with spatially or
temporally random defects as a consequence of interactions with random environments. We …

Unveiling hidden topological phases of a one-dimensional Hadamard quantum walk

H Obuse, JK Asbóth, Y Nishimura, N Kawakami - Physical review B, 2015 - APS
Quantum walks, whose dynamics is prescribed by alternating unitary coin and shift
operators, possess topological phases akin to those of Floquet topological insulators, driven …

Spectral theory of extended Harper's model and a question by Erdős and Szekeres

A Avila, S Jitomirskaya, CA Marx - Inventiones mathematicae, 2017 - Springer
The extended Harper's model, proposed by DJ Thouless in 1983, generalizes the famous
almost Mathieu operator, allowing for a wider range of lattice geometries (parametrized by …

Disordered quantum walks in one lattice dimension

A Ahlbrecht, VB Scholz, AH Werner - Journal of Mathematical Physics, 2011 - pubs.aip.org
We study a spin-| $\frac {1}{2} $| 1 2-particle moving on a one-dimensional lattice subject to
disorder induced by a random, space-dependent quantum coin. The discrete time evolution …

Anderson localization in generalized discrete-time quantum walks

I Vakulchyk, MV Fistul, P Qin, S Flach - Physical Review B, 2017 - APS
We study Anderson localization in a generalized discrete-time quantum walk—a unitary map
related to a Floquet driven quantum lattice. It is controlled by a quantum coin matrix which …
