摘要：

In this paper, we propose an optical scheme to almost completely teleport a two-mode four-component entangled coherent state in terms of optical devices such as nonlinear Kerr media, beam splitters, phase shifters and photon detectors. Different from those previous schemes in which exact photon number discrimination is needed, in our scheme one only needs to make 'yes' and 'no' measurements upon the photon numbers in related modes. This scheme can also be understood as an entanglement swapping protocol.
