Abstract

In quantum communication and quantum computing, the Bell state acts as an important role. For two qubit of discrete variable, Bell state is composted by two orthogonal to each other's physical state of a physical system. For the physical system consisting of continuous variables, a scheme is presented for generating the quasi-Bell-states of entangled squeezed states by using the Raman interaction of an -type three-level atom with squeezed vacuum states (SVS) cavity fields. In this scheme, an atom initially prepared in its ground state is injected in proper order into several cavities initially prepared each in the SVS. After the atom interacting with these cavities, the entanglement of at-om-cavity-field is generated. Afterwards, by measuring the atom we obtain the quasi-Bell-states of the entangled squeezed states. Also, the entanglement properties of bipartite entangled qua-si-Bell-states as well as multipartite entangled SVSs are discussed.
