Gapped Two-Body Hamiltonian Whose Unique Ground State Is Universal for One-Way Quantum Computation
TL;DR: In this paper, the ground state of a physically reasonable Hamiltonian made of two-body, nearest-neighbor interactions is introduced, composed of six-state particles on a hexagonal lattice, and a general method for analyzing its properties based on its projected entangled pair state representation.
Information scrambling in chaotic systems with dissipation
TL;DR: In this paper, a dissipative version of the out-of-time-ordered correlators (OTOC) of closed local quantum systems is defined and numerically studied in the presence of dissipation.

Flux-Fusion Anomaly Test and Bosonic Topological Crystalline Insulators
Michael Hermele,Xie Chen +1 more
TL;DR: In this article, the flux-fusion anomaly test was introduced to detect anomalous symmetry fractionalization patterns in two-dimensional symmetry-enriched topological (SET) phases.
Book ChapterDOI
Gapped Quantum Systems and Entanglement Area Law
TL;DR: In this paper, the authors introduce the entanglement area law and its constant correction, and the topological entropy of the ground states of many-body systems with an energy gap.
Book ChapterDOI
Local Transformations and Long-Range Entanglement
TL;DR: In this article, it was realized that the key microscopic feature of topologically ordered systems is the existence of long-range many-body entanglement in the ground-state wave function.
