Lower Bounds on the Squashed Entanglement for Multi-Party System [PDF]

open access: greenInternational Journal of Theoretical Physics, 2007
Squashed entanglement is a promising entanglement measure that can be generalized to multipartite case, and it has all of the desirable properties for a good entanglement measure.

Semidefinite programming lower bounds on the squashed entanglement [PDF]

open access: green, 2022
The squashed entanglement is a widely used entanglement measure that has many desirable properties. However, as it is based on an optimization over extensions of arbitrary dimension, one drawback of this measure is the lack of good algorithms to compute it.

On holographic entanglement entropy of Horndeski black holes [PDF]

open access: yesJournal of High Energy Physics, 2017
We study entanglement entropy in a particular tensor-scalar theory: Horndeski gravity. Our goal is two-fold: investigate the Lewkowycz-Maldacena proposal for entanglement entropy in the presence of a tensor-scalar coupling and address a puzzle existing ...

Fidelity of recovery, squashed entanglement, and measurement recoverability [PDF]

open access: greenPhysical Review A, 2015
This paper defines the fidelity of recovery of a tripartite quantum state on systems $A,\phantom{\rule{0.16em}{0ex}}B$, and $C$ as a measure of how well one can recover the full state on all three systems if system $A$ is lost and a recovery operation is performed on system $C$ alone.

Distributed Compression and Squashed Entanglement [PDF]

open access: green, 2008
A single quantum state can be shared by many distant parties. In this thesis, we try to characterize the information contents of such distributed states by defining the multiparty information and the multiparty squashed entanglement, two steps toward a general theory of multiparty quantum information.

Entanglement Monogamy via Multivariate Trace Inequalities [PDF]

open access: yesCommunications in Mathematical Physics, 2023
Entropy is a fundamental concept in quantum information theory that allows to quantify entanglement and investigate its properties, for example its monogamy over multipartite systems.

Ergodic edge modes in the 4D quantum Hall effect

open access: yesSciPost Physics, 2021
The gapless modes on the edge of four-dimensional (4D) quantum Hall droplets are known to be anisotropic: they only propagate in one direction, foliating the 3D boundary into independent 1D conduction channels.
