Noiseless Conditional Teleportation of a Single Photon
Original language description
We experimentally demonstrate the noiseless teleportation of a single photon by conditioning on quadrature Bell measurement results near the origin in phase space and thereby circumventing the photon loss that otherwise occurs even in optimal gain-tunedcontinuous-variable quantum teleportation. In general, thanks to this loss suppression, the noiseless conditional teleportation can preserve the negativity of the Wigner function for an arbitrary pure input state and an arbitrary pure entangled resourcestate. In our experiment, the positive value of the Wigner function at the origin for the unconditional output state, W?0; 0? ? 0.015 0.001, becomes clearly negative after conditioning, W?0; 0? ? ?0.025 0.005, illustrating the advantage of noiseless conditional teleportation.
