Multipartitioning topological phases by vertex states and quantum entanglement
We discuss multipartitions of the gapped ground states of (2+ 1)-dimensional topological
liquids into three (or more) spatial regions that are adjacent to each other and meet at points …

Deciphering the nonlocal entanglement entropy of fracton topological orders
The ground states of topological orders condense extended objects and support topological
excitations. This nontrivial property leads to nonzero topological entanglement entropy S …

Fusion rules from entanglement
We derive some of the axioms of the algebraic theory of anyon (Kitaev, 2006) from a
conjectured form of entanglement area law for two-dimensional gapped systems. We derive …

Exponential clustering of bipartite quantum entanglement at arbitrary temperatures
T Kuwahara, K Saito - Physical Review X, 2022 - APS
Many inexplicable phenomena in low-temperature many-body physics are a result of
macroscopic quantum effects. Such macroscopic quantumness is often evaluated via long …

Entanglement bootstrap approach for gapped domain walls
We develop a theory of gapped domain wall between topologically ordered systems in two
spatial dimensions. We find a new type of superselection sector—referred to as the parton …

Approximate quantum error correction revisited: introducing the alpha-bit
We establish that, in an appropriate limit, qubits of communication should be regarded as
composite resources, decomposing cleanly into independent correlation and transmission …

Multipartite quantum nonlocality and Bell-type inequalities in a spin-1/2 model with topological quantum phase transitions
ZY Sun, HX Wen, M Li, Y Li - Physical Review A, 2021 - APS
Multipartite quantum nonlocality and Bell-type inequalities are used to characterize quantum
correlations in an infinite-size bond-alternating spin-1 2 Heisenberg chain with next-nearest …

Persistent Topological Negativity in a High-Temperature Mixed-State
We study the entanglement structure of the Greenberger-Horne-Zeilinger (GHZ) state as it
thermalizes under a strongly-symmetric quantum channel describing the Metropolis …

Verlinde formula from entanglement
B Shi - Physical Review Research, 2020 - APS
We derive the Verlinde formula from a recently advocated set of axioms about entanglement
