Continuous Multipartite Entangled Representation and Its Wigner Operator and Marginal Distribution

By extending the EPR bipartite entanglement to multipartite case, we briefly introduce a continuous multipartite entangled representation and its canonical conjugate state in the multi-mode Fock space, analyze their schmidt decompositions and give their entangling operators. Furthermore, based on the above analysis we also find the n-mode Wigner operator. In doing so we may identify the physical meaning of the marginal distribution of the Wigner function.

A generalized two-mode entangled state： Its generation,properties, and applications

Frontiers of physics 2014年第4期9卷 451-459页

作者： kai-Min Zheng Shi-You Liu Hao-Liang Zhang Cun-Jin Liu Li-Yun Hu Center for Quantum Science and Technology College of Physics and Communication Electronics Jiangxi Normal University Nanchang 330022 China Key Laboratory of Optoelectronic and Telecommunication of Jiangxi Nanchang 330022 China

Using the technique of integration within an ordered product of operators we construct a generalized two-mode entangled state, which can be generated by an asymmetrical beam splitter （BS）. Some important properties of this state, such as orthogonality and schmidt decomposition, are also dis- cussed by deriving the expression of BS operator in coordinate representation. As its applications, to conjugate state, obtain operator identities, generate new squeezing operators （squeezed state） are also presented. It is shown that the fidelity of quantum teleportation can be enhanced under certain case by using the asymmetrical new squeezed state as entangled resource.
