Optimal entanglement criteria from trace invariants
Bivas Mallick, Aabhas Gulati, Ion Nechita
Randomized measurement protocols give experimental access to low-degree polynomial invariants of a quantum state rather than to the state itself, which raises the question of what…
Entanglement in the Dicke subspace
Aabhas Gulati, Ion Nechita, Clément Pellegrini
We provide a complete mathematical theory for the entanglement of mixtures of Dicke states. These quantum states form an important subclass of bosonic states arising in the study o…
Positive maps and extendibility hierarchies from copositive matrices
Aabhas Gulati, Ion Nechita, Sang-Jun Park
This work introduces and systematically studies a new convex cone of PCOP (pairwise copositive). We establish that this cone is dual to the cone of PCP (pairwise completely positiv…
Rank-based entanglement detection for bound entangled states
Aabhas Gulati
We develop a new method for entanglement detection in bipartite quantum states by using the violation of the rank-1-generated property of matrices. The positive-semidefinite matric…
Entanglement in cyclic sign invariant quantum states
Aabhas Gulati, Ion Nechita, Satvik Singh
We introduce and study bipartite quantum states that are invariant under the local action of the cyclic sign group. Due to symmetry, these states are sparse and can be parameterize…
