Floquet-Anderson localization in the Thouless pump and how to avoid it
András Grabarits, Attila Takács, Ion Cosma Fulga +1
We investigate numerically how onsite disorder affects conduction in the periodically driven Rice-Mele model, a prototypical realization of the Thouless pump. Although the pump is…
Coherent errors and readout errors in the surface code
Áron Márton, János K. Asbóth
We consider the combined effect of readout errors and coherent errors, i.e., deterministic phase rotations, on the surface code. We use a recently developed numerical approach, via…
Multiparticle quantum walk: a dynamical probe of topological many-body excitations
Bogdan Ostahie, Doru Sticlet, Cătălin Paşcu Moca +4
Recent experiments demonstrated that single-particle quantum walks can reveal the topological properties of single-particle states. Here, we generalize this picture to the many-bod…
Two particles on a chain with disordered interaction: Localization and dissociation of bound states and mapping to chaotic billiards
Hugo Perrin, János K. Asbóth, Jean-Noël Fuchs +1
We consider two particles hopping on a chain with a contact interaction between them. At strong interaction, there is a molecular bound state separated by a direct gap from a conti…
Topological delocalization in the completely disordered two-dimensional quantum walk
János K. Asbóth, Arindam Mallick
We investigate numerically and theoretically the effect of spatial disorder on two-dimensional split-step discrete-time quantum walks with two internal "coin" states. Spatial disor…
Poor man's topological quantum gate based on the Su-Schrieffer-Heeger model
Péter Boross, János K. Asbóth, Gábor Széchenyi +2
Topological properties of quantum systems could provide protection of information against environmental noise, and thereby drastically advance their potential in quantum informatio…
