A new optical scheme for quantum teleportation of superposed coherent states. (English) Zbl 1142.81311
Summary: We propose a new optical scheme for the quantum teleportation of superposed coherent states (SCSs) in terms of optical elements. Our scheme can realize a near-complete quantum teleportation of SCSs with arbitrary coefficients. Different from previous schemes, our protocol need only yes or no measurements of the photon numbers of the related modes instead of the exact measurements of the photon numbers in the previous schemes.
