Abstract: (4924 Views)
In this paper, we suggest a scheme which can produce various types of entangled states of the cavity field. In the scheme, cavities with different time evolution properties are utilized. the cavities are arranged such that, their time evolutions change alternately from JC- to anti-JC-like Hamiltonian. From this configuration, three-partite GHZ states can be generated. At last, it is illustrated that, in the multi-cavity set up, if one prepares all cavities with the same time evolution property, W state can be obtained. An important feature of the proposed scheme is the fact that, the results of the processes are independent of the result of atomic detection.
Keywords: Entangled state, Jaynes-Cummings interaction, anti-Jaynes-Cummings interaction, GHZ state, W state.
