Multipartite entanglement in heterogeneous systems

D Goyeneche, J Bielawski, K Życzkowski - Physical Review A, 2016 - APS
Heterogeneous bipartite quantum pure states, composed of two subsystems with a different
number of levels, cannot have both reductions maximally mixed. In this work, we …

Quantum k-uniform states for heterogeneous systems from irredundant mixed orthogonal arrays

S Pang, X Zhang, SM Fei, ZJ Zheng - Quantum Information Processing, 2021 - Springer

Existence of locally maximally entangled quantum states via geometric invariant theory

J Bryan, Z Reichstein, M Van Raamsdonk - Annales Henri Poincaré, 2018 - Springer
We study a question which has natural interpretations both in quantum mechanics and in
geometry. Let V_ 1, ⋯, V_ n V 1,⋯, V n be complex vector spaces of dimension d_ 1, ..., d …

Classification and measurement of multipartite entanglement by reconstruction of correlation tensors on an NMR quantum processor

V Gulati, Arvind, K Dorai - The European Physical Journal D, 2022 - Springer
We introduce a protocol to classify three-qubit pure states into different entanglement
classes and implement it on an NMR quantum processor. The protocol is designed in such a …

Criterion for SLOCC equivalence of multipartite quantum states
