摘要

We present the generation of six-particle Greenberger-Horne-Zeilinger(GHZ)states via deterministic entanglement concentration and generalize the scheme to the case of 2N particles.We show that arbitrary 2N-particle GHZ states can be obtained with certain probability via entanglement concentration.This may provide a new perspective for the preparation of multi-particle GHZ states.This study is also an exploration on the theory of deterministic entanglement concentration.
