Three generic types of couplings between two quantum bits (qubits), found in solid state qubits were considered. The Bell preparation was achieved by generating polarization entangled photon pairs using parametric down conversion. The Bell measurement step was achieved by a analysis between four single photon detectors located at the four output channels of a beam splitter followed by two two-channel polarizers. It was shown that the proper choice of non-local Bell states could simplify the implementation of quantum dense coding and quantum teleportation.
