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…
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…
Multipartite entanglement in the diagonal symmetric subspace
Jordi Romero-Pallejà, 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…
Entangled symmetric states and copositive matrices
Carlo Marconi, Albert Aloy, Jordi Tura +1
Entanglement in symmetric quantum states and the theory of copositive matrices are intimately related concepts. For the simplest symmetric states, i.e., the diagonal symmetric (DS)…
