Robustness of multiparty entanglement

Christoph Simon, Julia Kempe

Research output: Contribution to journalArticlepeer-review


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.
