    Abstract

    Three experimentally feasible schemes are proposed for generating multipartite entangled states of cold trapped ions. In the first scheme, a GHZ state can be simply synthesized in a single step. The second scheme is to prepare fully symmetric W states with two steps. The third scheme describes the sequential generation of linear cluster states. In addition, a method to create a larger cluster state was also presented by fuzing the end qubits of two smaller cluster states in order to decrease the distortion caused by decoherence, which can speed up the generation of large cluster states. The above schemes involve the collective interaction between multiple ions with the vibrational ground state and a large detuned laser. Compared with previous schemes, the above schemes have four advantages. Firstly, they do not require the vibrational mode of ions as memory. Secondly, they do not need to address the ions individually. Thirdly, they are free from the effects of phase fluctuation of laser field. Finally, they need less operations.
