  The preparation of multipartite entangled states is the prerequisite for
exploring quantum information networks and quantum computation. In this letter,
we present the first experimental demonstration of eight-partite spatially
separated CV entangled states. The initial resource quantum states are eight
squeezed states of light, through the linearly optical transformation of which
two types of the eight-partite cluster entangled states are prepared,
respectively. The generated eight entangled photonic qumodes are spatially
separated, which provide valuable quantum resources to implement more
complicated quantum information task.
