    "abstract": "We propose an entanglement purification protocol for high-dimensional\nmultipartite systems. In the protocol we can select a subensemble in a pure\ngeneralized Greenberger-Horne-Zeilinger (GHZ) state. This post-selection can be\nmade by detecting the noise which contaminated the initial pure ensemble when\nthe systems past through a noisy environment. For the detection of noise we\ninvestigate correlation properties of GHZ states and analyze their possible\nerrors due to a noisy environment. We show that the presented protocol is more\nefficient than a simple generalization of the purification protocol for a\nbipartite state in high dimensions.",
