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…
A Short Course on Topological Insulators: Band-structure topology and edge states in one and two dimensions
János K. Asbóth, László Oroszlány, András Pályi
This course-based primer provides newcomers to the field with a concise introduction to some of the core topics in the emerging field of topological band insulators in one and two…
Bulk--Boundary Correspondence for Chiral Symmetric Quantum Walks
János. K. Asbóth, Hideaki Obuse
Discrete-time quantum walks (DTQW) have topological phases that are richer than those of time-independent lattice Hamiltonians. Even the basic symmetries, on which the standard cla…
