Entangled symmetric states and copositive matrices

Carlo Marconi, Albert Aloy, Jordi Tura, and Anna Sanpera,

Quantum 5, 561 (2021).

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) states, i…

Diagonal unitary and orthogonal symmetries in quantum theory

Satvik Singh and Ion Nechita,

Quantum 5, 519 (2021).

We analyze bipartite matrices and linear maps between matrix algebras, which are respectively, invariant and covariant, under the diagonal unitary and orthogonal groups' actions. By presenti…

Separability of diagonal symmetric states: a quadratic conic optimization problem

Jordi Tura, Albert Aloy, Ruben Quesada, Maciej Lewenstein, and Anna Sanpera,

Quantum 2, 45 (2018).

We study the separability problem in mixtures of Dicke states i.e., the separability of the so-called Diagonal Symmetric (DS) states. First, we show that separability in the case of DS in…
