Journal ArticleDOI
Observation of topological edge states in parity-time-symmetric quantum walks
Lei Xiao,Xiang Zhan,Zhihao Bian,Kunkun Wang,X. Zhang,X. P. Wang,Jian Li,Ken Mochizuki,Dakyeong Kim,Norio Kawakami,Wei Yi,Hideaki Obuse,Barry C. Sanders,Peng Xue,Peng Xue +14 more
TL;DR: In this article, spontaneous parity and topological edge states are observed in a photonic non-Hermitian system with a quantum walk interferometer, where topological parity is achieved by time symmetry breaking.
Journal ArticleDOI
Non-Hermitian bulk-boundary correspondence in quantum dynamics
TL;DR: In this paper, the non-Hermitian bulk-boundary correspondence was shown to hold for a wide range of open topological systems with effective non-Bloch Hamiltonians.
Journal ArticleDOI
Observation of non-Hermitian bulk-boundary correspondence in quantum dynamics
TL;DR: In this paper, the authors theoretically predict and experimentally observe non-Hermitian bulk-boundary correspondence in discrete-time quantum-walk dynamics of single photons, and demonstrate photon localizations near boundaries even in the absence of topological edge states.
Journal ArticleDOI
Detecting topological invariants in nonunitary discrete-time quantum walks
Xiang Zhan,Lei Xiao,Zhihao Bian,Kunkun Wang,Xingze Qiu,Barry C. Sanders,Wei Yi,Peng Xue,Peng Xue +8 more
TL;DR: The experimental detection of bulk topological invariants in nonunitary discrete-time quantum walks with single photons is reported and the robustness of both the topological properties and the measurement scheme of the topology invariants against disorder is demonstrated.
Journal ArticleDOI
Simulating Dynamic Quantum Phase Transitions in Photonic Quantum Walks.
TL;DR: This experiment directly confirms the relation between DQPTs and DTOPs in quench dynamics of topological systems and opens up the avenue of simulating emergent topological phenomena using discrete-time quantum-walk dynamics.
