Robustness of multiparty entanglement

Christoph Simon, Julia Kempe

Research output: Contribution to journalArticle


The robustness of multiparty entanglement was studied under local decoherence. The robustness of entanglement was found to increase with the number of qubits. It was found that Greenberger-Horne-Zeilinger (GHZ) states were more robust than other generic states of three and four qubits. The spin-squeezed states were also studied in the limit n→∞ and were found to be able to stand considerable local depolarization.
