外文摘要：The Greenberger-Horne-Zeilinger(GHZ)paradox shows that it is possible to create a multipartite state involving three or more particles in which the measurement outcomes of the particles are correlated in a way that cannot be explained by classical physics.We extend it to witness quantum networks.We first extend the GHZ paradox to simultaneously verify the GHZ state and Einstein-Podolsky-Rosen states on triangle networks.We then extend the GHZ paradox to witness the entanglement of chain networks consisting of multiple GHZ states.All the present results are robust against the noise.
