Abstract
In this brief report we present a feasible scheme to split quantum information in the realm of traveling waves. An oversimplified scheme is also proposed for the generation of a class of W states useful for perfect teleportation and superdense coding. The scheme employs only linear optical elements as beam splitters and phase shifters, in addition to photon counters and one-photon sources. It is shown that splitting of quantum information with high fidelity is possible even including inefficiency of the detectors and photoabsorption of the beam splitters.
