Journal ArticleDOI
Photons walking the line: A quantum walk with adjustable coin operations
Andreas Schreiber,Katiuscia N. Cassemiro,Václav Potoček,Aurél Gábris,Peter J. Mosley,Erika Andersson,Igor Jex,Ch Silberhorn +7 more
TL;DR: The first robust implementation of a coined quantum walk over five steps using only passive optical elements is presented, observing a non-Gaussian distribution of the walker's final position, thus characterizing a faster spread of the photon wave packet in comparison to the classical random walk.
Journal ArticleDOI
A 2D Quantum Walk Simulation of Two-Particle Dynamics
Andreas Schreiber,Andreas Schreiber,Aurél Gábris,Aurél Gábris,Peter P. Rohde,Peter P. Rohde,Kaisa Laiho,Kaisa Laiho,M. Štefaňák,Václav Potoček,Craig S. Hamilton,Igor Jex,Christine Silberhorn,Christine Silberhorn +13 more
TL;DR: An optical system is demonstrated that can simulate quantum walks over a two-dimensional system, thereby providing the capability of describing much more complex processes and illustrating the potential of quantum walks as a route for simulating and understanding complex quantum systems.
Journal ArticleDOI
Decoherence and Disorder in Quantum Walks: From Ballistic Spread to Localization
Andreas Schreiber,Katiuscia N. Cassemiro,Václav Potoček,Aurél Gábris,Igor Jex,Christine Silberhorn,Christine Silberhorn +6 more
TL;DR: This work investigates the impact of decoherence and static disorder on the dynamics of quantum particles moving in a periodic lattice and simulates three different environmental influences on the system, resulting in a fast ballistic spread, a diffusive classical walk, and the first Anderson localization in a discrete quantum walk architecture.
Journal ArticleDOI
Optimized quantum random-walk search algorithms on the hypercube
TL;DR: Improvements to the SKW algorithm are presented which yield a significant increase in success probability, and an improvement on query complexity such that the theoretical limit of a search algorithm succeeding with probability close to one is reached.
Journal ArticleDOI
Measuring topological invariants in disordered discrete-time quantum walks
Sonja Barkhofen,Thomas Nitsche,Fabian Elster,Lennart Lorz,Aurél Gábris,Aurél Gábris,Igor Jex,Christine Silberhorn +7 more
TL;DR: In this article, the authors implemented the scattering scheme proposed by Tarasinski et al. in a photonic time multiplexed quantum walk experiment to directly measure the topological invariants of quantum walks.
