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 …

Experimental realization of Dicke states of up to six qubits for multiparty quantum networking

R Prevedel, G Cronenberg, MS Tame, M Paternostro… - Physical review …, 2009 - APS
We report the first experimental generation and characterization of a six-photon Dicke state.
The produced state shows a fidelity of F= 0.56±0.02 with respect to an ideal Dicke state and …

We compute the complete one-loop finite temperature effective potential for electroweak
symmetry breaking in the Standard Model with a Higgs potential supplemented by higher …

Majorana representation of symmetric multiqubit states

ARU Devi, Sudha, AK Rajagopal - Quantum Information Processing, 2012 - Springer
As early as 1932, Majorana had proposed that a pure permutation symmetric state of N spin-
1 2 particles can be represented by N spinors, which correspond geometrically to N points …

Operational Families of Entanglement Classes for Symmetric -Qubit States

T Bastin, S Krins, P Mathonet, M Godefroid, L Lamata… - Physical review …, 2009 - APS
We solve the entanglement classification under stochastic local operations and classical
communication (SLOCC) for all multipartite symmetric states in the general N-qubit case. For …

A diagrammatic axiomatisation for qubit entanglement

A Hadzihasanovic - 2015 30th Annual ACM/IEEE Symposium …, 2015 - ieeexplore.ieee.org
Diagrammatic techniques for reasoning about monoidal categories provide an intuitive
understanding of the symmetries and connections of interacting computational processes. In …

Four-qubit entanglement classification from string theory

L Borsten, D Dahanayake, MJ Duff, A Marrani… - Physical review …, 2010 - APS
We invoke the black-hole–qubit correspondence to derive the classification of four-qubit
entanglement. The U-duality orbits resulting from timelike reduction of string theory from D …

The compositional structure of multipartite quantum entanglement

B Coecke, A Kissinger - International Colloquium on Automata, Languages …, 2010 - Springer
Multipartite quantum states constitute a (if not the) key resource for quantum computations
and protocols. However obtaining a generic, structural understanding of entanglement in N …

L Borsten, MJ Duff, P Lévay - Classical and Quantum Gravity, 2012 - iopscience.iop.org
We give a review of the black-hole/qubit correspondence that incorporates not only the
earlier results on black-hole entropy and entanglement measures, seven qubits and the …

Classification of four-qubit entangled states via machine learning

SV Vintskevich, N Bao, A Nomerotski, P Stankus… - Physical Review A, 2023 - APS
We apply the support vector machine (SVM) algorithm to derive a set of entanglement
witnesses (EW) to identify entanglement patterns in families of four-qubit states. The …
