Entanglement constraints in various symmetric subspaces
Presenting Author: Alexander Meill, University of California San Diego
Contributing Author(s): David Meyer
We simplify the search for constraints on multi-partite entanglement by restricting the calculations to Hilbert spaces of 3-5 qubits which exhibit relevant symmetries. In 3 qubits we describe the space of achievable local unitary polynomial invariants among states which are fully symmetric under party relabeling. In 4 and 5 qubits we discuss pairwise concurrence relations in states which are invariant under cyclic permutation of the party labels.
