  • The experimentally feasible scheme of re-
    motely generating continuous variable quantum entangled
    communication channel based on beam splitters is pro-
    posed. It is showed that the long-haul quantum communi-
    cation channel can be established by means of an assisted
    single-photon entangled state and a pair of single-mode
    squeezed vacuum states. The degree of entanglement of
    the desired continuous variable entangled channel is only
    related with the assisted beam splitter when the other two
    parallel ones are of the same parameter values. The suc-
    cess probability of creating maximal entangled channel can
    be enhanced with the increasing of beam splitter re°ec-
    tion coe±cients and decreasing of squeezing parameters.
    Furthermore, the puri¯cation of success probability is dis-
    cussed for imperfect photo-detectors.
