Abstract
We proposal an experimental scheme of continuous variables quantum teleportation, in which the entangled EPR source are generated by phase-sensitive parametric amplified four-wave mixing. The Bell state measurement is accomplished by means of direct detection for photocurrents and two RF power splitters. It is worth mentioning that the scheme does not require a local oscillator and balanced homodyne detector. Combined with the simple experimental apparatus of parametric amplified four-wave mixing, the proposed system is easily implemented in experiments.
