Abstract
Entanglement of energy-time is used as an ancillary to analyze four polarization entangled Bell-states. The scheme requires only linear optics and single photon detectors, and is realizable with current technology. The overall efficiency is 50%. This Bell-states measurement scheme is useful for quantum dense coding and quantum teleportation protocols.
