Quantifying entanglement resources

C Eltschka, J Siewert - Journal of Physics A: Mathematical and …, 2014 - iopscience.iop.org
We present an overview of the quantitative theory of single-copy entanglement in finite-
dimensional quantum systems. In particular we emphasize the point of view that different …

Multipartite entanglement measures

S Szalay - Physical Review A, 2015 - APS
The main concern of this paper is how to define proper measures of multipartite
entanglement for mixed quantum states. Since the structure of partial separability and …

Monogamy of quantum entanglement

XL Zong, HH Yin, W Song, ZL Cao - Frontiers in Physics, 2022 - frontiersin.org
Unlike classical correlation, quantum entanglement cannot be freely shared among many
parties. This restricted shareability of entanglement among multi-party systems is known as …

Tripartite entanglement in a noninertial frame

MR Hwang, DK Park, E Jung - Physical Review A—Atomic, Molecular, and …, 2011 - APS
Tripartite entanglement is examined when one of the three parties moves with a uniform
acceleration with respect to other parties. As the Unruh effect indicates, tripartite …

Entanglement of three-qubit greenberger-horne-zeilinger–symmetric states

C Eltschka, J Siewert - Physical review letters, 2012 - APS
The first characterization of mixed-state entanglement was achieved for two-qubit states in
Werner's seminal work [Phys. Rev. A 40, 4277 (1989) PLRAAN 0556-2791 …

Strong monogamy conjecture for multiqubit entanglement: The four-qubit case

B Regula, S Di Martino, S Lee, G Adesso - Physical review letters, 2014 - APS
We investigate the distribution of bipartite and multipartite entanglement in multiqubit states.
In particular, we define a set of monogamy inequalities sharpening the conventional …

Complete complementarity relations for multipartite pure states

MLW Basso, J Maziero - Journal of Physics A: Mathematical and …, 2020 - iopscience.iop.org
Complementarity relations for wave-particle duality are saturated only for pure, single-
quanton, quantum states. For a completely incoherent state, it is known that wave and …

Variational approach to the quantum separability problem

M Consiglio, TJG Apollaro, M Wieśniak - Physical Review A, 2022 - APS
We present the variational separability verifier (VSV), which is a variational quantum
algorithm that determines the closest separable state (CSS) of an arbitrary quantum state …

Parametrized entanglement monotone

X Yang, MX Luo, YH Yang, SM Fei - Physical Review A, 2021 - APS
Entanglement concurrence has been widely used for featuring entanglement in quantum
experiments. As an entanglement monotone it is related to specific quantum Tsallis entropy …

Quantifying tripartite entanglement of three-qubit generalized Werner states

J Siewert, C Eltschka - Physical review letters, 2012 - APS
Multipartite entanglement is a key concept in quantum mechanics for which, despite the
experimental progress in entangling three or more quantum devices, there is still no general …
