| Abstract: | We propose a nearly perfect optical scheme for the quantum teleportation of
entangled coherent states using optical devices such as nonlinear Kerr media, beam
splitters, phase shifters, and photon detectors. Different from those previous
schemes, our scheme needs only ``yes' or `no' measurements of the photon number of
the related modes, i.e. nonzero- and zero-photon measurements, while in previous
schemes one has to exactly identify the even or odd parity character of the photon
numbers detected by detectors. |
