Partial Bell-State Analysis with Parametric down Conversion in the Wigner Function Formalism

Figure 1

Setup for quantum dense coding. The polarization rotator and the wave retarder used by Bob allow a transmission to Alice of any of the Bell-states. Alice’s station consists on a balanced beam-splitter, two polaryzing beam-splitters, and detectors DH1, DV1, DH2, and DV2.
