Cullen AR., Kok P.”Calculating concentratable entanglement in graph states”, Phys. Rev. A 106, 042411, 2022. DOI: 10.1103/PhysRevA.106.042411
We propose a method to calculate the purity of reduced states of graph states entirely within the stabilizer formalism, using only the stabilizer generators for a given state. We apply this method to find the concentratable entanglement of graph states, with examples including a single qubit within any graph state, states proposed for use in quantum repeaters, and states that maximize and minimize the overall concentratable entanglement.
