Fraction of isospectral states exhibiting quantum correlations
Michał Oszmaniec, Marek Kuś
For several types of correlations: mixed-state entanglement in systems of distinguishable particles, particle entanglement in systems of indistinguishable bosons and fermions and n…
A universal framework for entanglement detection
Michał Oszmaniec, Marek Kuś
We construct nonlinear multiparty entanglement measures for distinguishable particles, bosons and fermions. In each case properties of an entanglement measures are related to the d…
How many invariant polynomials are needed to decide local unitary equivalence of qubit states?
Tomasz Maciazek, Michał Oszmaniec, Adam Sawicki
Given L-qubit states with the fixed spectra of reduced one-qubit density matrices, we find a formula for the minimal number of invariant polynomials needed for solving local unitar…
Geometry and topology of CC and CQ states
Michał Oszmaniec, Piotr Suwara, Adam Sawicki
We show that multipartite mixed bipartite CC and CQ states are geometrically and topologically distinguished in the space of states. They are characterized by non-vanishing Euler-P…
