Entanglement constrained by superselection rules.

Ferreting out the Fluffy Bunnies: Entanglement Constrained by Generalized Superselection Rules

Entanglement is a resource central to quantum information (QI). In particular, entanglement shared between two distant parties allows them to do certain tasks that would otherwise be impossible. In this context, we study the effect on the available entanglement of physical restrictions on the local operations that can be performed by the two parties. We enforce these physical restrictions by ge...
