Three methods to distill multipartite entanglement over bipartite noisy channels

We first assume that there are only bipartite noisy qubit channels in a given multipartite system, and present three methods to distill the general Greenberger–Horne–Zeilinger state. By investigating the methods, we show that multipartite entanglement distillation by bipartite entanglement distillat...

Summary:We first assume that there are only bipartite noisy qubit channels in a given multipartite system, and present three methods to distill the general Greenberger–Horne–Zeilinger state. By investigating the methods, we show that multipartite entanglement distillation by bipartite entanglement distillation has higher yield than ones in the previous multipartite entanglement distillations.
