Entanglement in the symmetric subspace: mapping multipartite to bipartite states
Carlo Marconi, Satoya Imai
We propose a technique to investigate multipartite entanglement in the symmetric subspace. Our approach is to map an -qubit symmetric state onto a bipartite symmetric state of h…

Symmetric quantum states: a review of recent progress
Carlo Marconi, Guillem Müller-Rigat, Jordi Romero-Pallejà +2
Symmetric quantum states are fascinating objects. They correspond to multipartite systems that remain invariant under particle permutations. This symmetry is reflected in their com…

Multipartite entanglement in the diagonal symmetric subspace
Jordi Romero-PallejÃ, Jennifer Ahiable, Alessandro Romancino +2
We investigate the entanglement properties in the symmetric subspace of -partite -dimensional systems (qudits). For diagonal symmetric states, we show that there is no bound…
